Observers have long noted a distinctive greenish tint to the nebula, in addition to regions of red and of blue-violet. The red hue is a result of the Hα recombination line radiation at a wavelength of 656.3 nm. The blue-violet coloration is the reflected radiation from the massive O-class stars at the core of the nebula. The green hue was a puzzle for astronomers in the early part of the 20th century because none of the known spectral lines at that time could explain it.

UDO systems use a blue-violet laser operating at a wavelength of 405 nm, similar to the one used in Blu-ray Disc, to read and write data. Conventional MOs use red lasers at 660 nm. The blue- violet laser's shorter wavelength makes it possible to store more information on a 13 cm sized UDO disc. The minimum "spot size" on which a laser can be focused is limited by diffraction, and depends on the wavelength of the light and the numerical aperture of the lens used to focus it.

The importance of colour is linked to Messiaen's synaesthesia, which he said caused him to experience colours when he heard or imagined music (he said that he did not perceive the colours visually). In his multi-volume music theory treatise Traité de rythme, de couleur, et d'ornithologie ("Treatise of Rhythm, Colour and Birdsong"), Messiaen wrote descriptions of the colours of certain chords. His descriptions range from the simple ("gold and brown") to the highly detailed ("blue-violet rocks, speckled with little grey cubes, cobalt blue, deep Prussian blue, highlighted by a bit of violet-purple, gold, red, ruby, and stars of mauve, black and white. Blue- violet is dominant").

If D is greater than zero, the medium has negative dispersion. If a light pulse is propagated through a normally dispersive medium, the result is the higher frequency components slow down more than the lower frequency components. The pulse therefore becomes positively chirped, or up-chirped, increasing in frequency with time. This causes the spectrum coming out of a prism to appear with red light the least refracted and blue/violet light the most refracted.

Headlamps are generally required to produce white light, according to both ECE and SAE standards. ECE Regulation 48 currently requires new vehicles to be equipped with headlamps emitting white light. Different headlamp technologies produce different characteristic types of white light; the white specification is quite large and permits a wide range of apparent colour from warm white (with a brown-orange-amber-yellow cast) to cold white (with a blue-violet cast).

In Messianic Judaism the blue-violet tekhelet thread is always included in the tzitziyot. This thread is thought to be representative of Jesus, whom they believe to be the Messiah. Beyond this requirement, there is a wider variety of interpretations for the proper way to wear tzitzit than in Judaism. Some include other colors of thread as well, as there is no negative commandment not to wear other colors in the tzitziyot.

The cross section of an Eagle Fern shows the bright green and bright blue fluorescence seen with CFW. Solutions that are aqueous for calcofluor-white have an absorption spectrum from 300 to 412 nm with a peak at 347 nm. The peak of fluorescence occurs best with ultraviolet light, but violet/blue violet also gives great results of fluorescence. Calcofluor-White is an fluorescent dye, meaning it has an excitation and emission wavelength that differs from one another.
|
|
The excitation wavelength is 380 nm while the emission is 475 nm. The fluorescence can best be seen with ultraviolet light, but it can also be seen with violet or blue violet. Fungi tend to display a bright green color under UV/violet/violet-blue light due to the barrier filters used in microscopy for fluorescence. Calcofluor white has to careful interpretation of staining as some non-specific reactions can make the background look a fluorescent yellow-green color.

The life cycle of Speyeria zerene begin when the pink-tan colored eggs hatch. Females lay these eggs on the dried stems and debris of the blue violet (Viola adunca). The larvae, which have spikes on their backs and are dark in color, emerge in the spring. The larvae grow in six stages of development (instars) and feed on the violet until it is time for the larvae to pupate, which they do on the violet.

The optic properties of water also lead to different wavelengths of light being absorbed to different degrees, for example light of long wavelengths (e.g. red, orange) is absorbed quite quickly compared to light of short wavelengths (blue, violet), though ultraviolet light (even shorter wavelength than blue) is absorbed quite quickly as well. Besides these universal qualities of water, different bodies of water may absorb light of different wavelengths because of salts and other chemicals in the water.

The intense radiation in the first seconds after the blast may cause an observable aura of fluorescence, the blue-violet-purple glow of ionized oxygen and nitrogen out to a significant distance from the fireball, surrounding the head of the forming mushroom cloud. This light is most easily visible at night or under conditions of weak daylight. The brightness of the glow decreases rapidly with elapsed time since the detonation, becoming only barely visible after a few tens of seconds.

The diet of Speyeria zerene varies throughout its life history. When the larva emerges in the spring the diet consists solely on the leaves of the blue violet (Viola adunca). When the adult emerges from its chrysalis it will feed solely on nectar of flowers. It feeds on a variety of plants including ones from the family Asteraceae, its main source of nutrition, but other families of plants that the butterfly may feed on include thistles, asters, yarrow, and pearly everlasting.

Readout of a PSP plate A lower-frequency light source that is insufficient in energy to create more Eu3+ ions can return the trapped electrons to the conduction band. As these mobilized electrons encounter Eu3+ ions, they release a blue-violet 400 nm luminescence. This light is produced in proportion to the number of trapped electrons, and thus in proportion to the original X-ray signal. It can be collected often by a photomultiplier tube, which is clocked at a specific resolution or pixel capture frequency.

When looked at through a prism, the colours seen at a light–dark boundary depend upon the orientation of this light–dark boundary. When viewed through a prism, the orientation of a light–dark boundary with respect to the prism's axis is significant. With white above a dark boundary, we observe the light extending a blue-violet edge into the dark area; whereas dark above a light boundary results in a red-yellow edge extending into the light area. Goethe was intrigued by this difference.

See CIE for the standard representation of color space, where the border is composed of a horseshoe curve representing the pure spectral colors, with a straight line completing the perimeter along the bottom and representing the mixtures of extreme red and blue/violet that give the pure purples. The same argument applies to complementary colors; for many coordinates in the green area of CIE color space, there is a proper dominant wavelength but no proper complementary wavelength, but there is a complementary purple hue.

Becquerel was an early experimenter in photography. In 1840, he discovered that the silver halides, natively insensitive to red and yellow light, became sensitive to that part of the spectrum in proportion to their exposure to blue, violet and ultraviolet light, allowing daguerreotypes and other photographic materials to be developed by bathing in strong red or yellow light rather than by chemical treatment.E. Becquerel (1840). "Mémoire sur le rayonnement chimique qui accompagne la lumière solaire et la lumière électrique", Comptes Rendus 11:702–703.

Tanzanite can also appear differently when viewed under different lighting conditions. The blues appear more evident when subjected to fluorescent light and the violet hues can be seen readily when viewed under incandescent illumination. In its rough state tanzanite is colored a reddish brown to clear, and it requires heat treatment to remove the brownish "veil" and bring out the blue violet of the stone. The gemstone was given the name 'tanzanite' by Tiffany & Co. after Tanzania, the country in which it was discovered.

In Paris friends and acquaintances sent bouquets of flowers weekly for his still life paintings. He also purchased bouquets inexpensively, choosing flowers in a variety of colors for his paintings. In a letter to his sister Wil he wrote, "Last year I painted almost nothing but flowers so I could get used to colors other than grey - pink, soft or bright green, light blue, violet, yellow, glorious red." That was an exaggeration; during his time in Paris he painted 230 paintings, about 30 of which were flowers.

Kapsai women wore long, wide dress garments with large designs of stars and tulips, semidark in colour and partially striped. The Zanavykai costume is one of the most decorative in design, colour and style. Suvalkija women wore wide, gathered skirts of one main color (dark and rich, such as dark red, blue, violet, or green) with narrow multi-colored stripes woven into the fabric. Women's blouses in Suvalkija are distinguishable from those of other regions by their wider sleeves and by more extensive decorations.

In one version of Maiden’s Lament,Maiden’s Lament the narrator tells her audience to keep their gardens fair and not to let anyone steal their thyme. Once, she had a sprig of thyme but a gardener’s son came with a red rose, a blue violet and some bitter rue. He stole the thyme and left only rue, with its "running root", growing in its place. Her parents were angry but she will cut the head off the rose and plant a willow for all to see.

Four-spotted chaser on its perch The male is considered to be highly aggressive and will defend a given territory from incursions from other males of the species. The male is known to form preferences for prominent perches and will often return to the same perches around the margins of pools and ponds whilst it patrols for intruders. Males have a favourable view of the sky during perching. They look toward a section of the sky away from the sun, with less radiation but a higher UV and blue-violet saturation.

Thus was produced his own brushwork, his distinctive, spirited style. The artist proceeds to the contrast of red and green, orange and yellow and blue- violet, red and white, through a variety of means - mosaics, murals, most of all - to oil painting, pastels and various drawing tools. From the last time (since 1990) the main formative role in his artistic style plays a pure color that enhances the activity of emotional pictures and highlights the decorative solution compositions. Patyk is very close to Ukrainian icon and Tuscan primitives, Ravenna mosaics and Italian painters of Protorenaissance.

By wearing long skirts, she was somewhat out of style with the new fad being flapper dresses, but Florence remarked that she had no right to dictate how short the skirts should be. In addition, she launched new fashions like the silk black neckband, which became known as "Flossie Clings" after her maiden name. She carried small bouquets of blue-violet flowers to complement her blue eyes. Despite her emphasis on fashion, Florence was economical elsewhere in the White House budget, which was highly praised in the wake of the 1921 recession.

About twenty female ray florets have blue violet straps of about long and 1 mm (0.04 in) wide. In the center of the head are many yellow, bisexual disc florets of about 2 mm (0.1 in) long. In the center of the corolla of each disc floret are five anthers merged into a tube, through which the style grows when the floret opens, hoovering up the pollen on its shaft. The style in both ray- and disc florets forks, and at the tip of both style branches is a broadly triangular appendage.

Contrary to popular belief, the peak absorption frequency for L, M, and S cones do not exactly correspond to red, green, and blue wavelength. Rather, the peak frequency for the L cone is orange, yellowish green in M cones, and blue-violet in S cones. These cones transduce the absorbed light into electrical information to be relayed to neurons in the retina such as retinal bipolar cells and retinal ganglion cells, before reaching the brain. The signals from different cones are added or subtracted from each other to process the color of incoming light.

Murray primarily worked with watercolours. Watercolour began to be used in England at the beginning of the 18th century, using the "traditional English method" which consisted of superimposing fine layers of carefully mixed colours to create the intended effects of colour and depth. However, Murray didn't use the traditional methods, but instead usually used the gouache technique in her works. Her works stand out for their colourful palette, in which she abundantly used chestnut, blue, violet, pink, black, scarlet, and gold, as well as olive and tar colours applied in bright and intense shades.

The spectral G-Index is a variable that was developed to quantify the amount of short wavelength light in a visible light source relative to its visible emission (it is a measure of the amount of blue light per lumen). The smaller the G-index, the more blue, violet, or ultraviolet light a lamp emits relative to its total output. It is used in order to select outdoor lamps that minimize skyglow and ecological light pollution. The G-index was originally proposed by David Galadí Enríquez, an astrophysicist at Calar Alto Observatory.

Gentiana puberulenta, the downy gentian, is a branchless perennial plant of the Gentianaceae family native to North America. It is about ¾–1½' tall, with bright blue to deep blue-violet bell-shaped, upright, five-lobed flowers measuring 1½ to 2¼ inches across when fully open. Flowers grow in clusters of 1–8 at the apex of the plant. Lanceolate, sessile, glossy leaves up to 3" long and 1¼" across are arranged oppositely along the central stem, except at the apex where they grow in whorls of 3–7.

Example of Karaite tzitziyot Karaite Jews maintain that the tzitziyot must be braided and have the appearance of chains, rather than being knotted as are the tzitziyot of Rabbinic Judaism. Karaites tzitziyot have blue-violet threads (tekhelet) in them. In contrast to rabbinic Jews, Karaites believe that the tekhelet source can be any dye, except those produced from impure (a definition mostly overlapping "un-kosher") species, such as the molluscs used by Rabbinic Jews. Instead, Karaites propose that the source of the dye was indigo or woad (Isatis tinctoria).

The IUCAA Faint Object Spectrograph and Camera (IFOSC) is the main instrument available on the telescope's main Cassegrain port. IFOSC employs an EEV 2K x 2K, thinned, back-illuminated CCD with 13.5 micrometer pixels. The spatial sampling scale at the detector is 44μm per arcsecond giving a field of view of about 10.5 arcminutes on the side. In addition to ultraviolet, blue, violet, red, infrared imaging and photometric capabilities, IFOSC offers a range of grisms with resolutions ranging from 190 to 3700 covering the wavelength region of 350–850 nm.

The temperature of the envelope must be carefully controlled, since the behaviour of the arc is determined largely by the vapor pressure of the mercury, which in turn is set by the coolest spot on the enclosure wall. A typical design maintains temperature at and a mercury vapor pressure of 7 millipascals. The mercury ions emit light at characteristic wavelengths, the relative intensities of which are determined by the pressure of the vapor. At the low pressure within a rectifier, the light appears pale blue-violet and contains much ultraviolet light.

Just as the synthetic cannabinoid(s) used differ between each synthetic cannabinoid product sold, so do the other contents of the "herbal blends." Packages of synthetic cannabinoid products can claim to contain a wide array of plants including alfalfa, blue violet, nettle leaf, marsh mallow, rosehip, white or blue water lily, honeyweed, dwarf skullcap, and others. Oftentimes, none of the listed ingredients have been detectable. It is often difficult to determine what is in these products because masking agents, such as tocopherol (vitamin E), eugenol, and fatty acids, are added to confound identification.

Panchromatic films and papers, nominally sensitive to the entire spectrum, sometimes have a region of minimum in their range of sensitivity that allows the careful use of safelight confined to that part of the spectrum. For example, Kodak Panalure panchromatic paper is tolerant of limited exposure to light filtered through a Kodak 13 Safelight Filter. Other panchromatic materials must be handled only in total darkness. Many photosensitive materials used in technical and industrial applications, such as photoresist, are sensitive only to blue, violet, and ultraviolet light and may be handled under a brighter yellow safelight.

When dissolved in water, the dye has a blue-violet colour with an absorbance maximum at 590 nm and an extinction coefficient of 87,000 M−1 cm−1. The colour of the dye depends on the acidity of the solution. At a pH of +1.0, the dye is green with absorption maxima at 420 nm and 620 nm, while in a strongly acidic solution (pH −1.0), the dye is yellow with an absorption maximum at 420 nm. The different colours are a result of the different charged states of the dye molecule.

Solar glory at the steam from a right A common optical phenomenon involving water droplets is the glory. A glory is an optical phenomenon, appearing much like an iconic Saint's halo about the head of the observer, produced by light backscattered (a combination of diffraction, reflection and refraction) towards its source by a cloud of uniformly sized water droplets. A glory has multiple colored rings, with red colors on the outermost ring and blue/violet colors on the innermost ring. The angular distance is much smaller than a rainbow, ranging between 5° and 20°, depending on the size of the droplets.

Neil McKenna, who wrote a biography of Boulton and Park, described Boulton as "pretty with his blue-violet eyes, large as saucers in his pale face, and his dark hair cascading in baby curls"; McKenna notes that as a child, Boulton was often mistaken as a baby girl. From the time he was six Boulton began dressing up and acting as a girl, often as a parlourmaid. He once dressed up and served his unknowing grandmother at the dinner table. When he left the room, she commented to Boulton's mother "I wonder, having sons, that you have so flippant a girl about you".

New Zealand Vehicle Inspection Requirement Manual p. 4.1.2 The intent of selective yellow is to improve vision by removing short, blue to violet wavelengths from the projected light. These wavelengths are difficult for the human visual system to process properly, and they cause perceived dazzle and glare effects in rain, fog and snow. Removing the blue-violet portion of a lamp's output to obtain selective yellow light can entail filter losses of around 15%, though the effect of this reduction is said to be mitigated or countervailed by the increased visual acuity available with yellow rather than white light in bad weather.

In 1873 Vogel discovered dye sensitization, a pivotal contribution to the progress of photography. The photographic emulsions in use at that time were sensitive to blue, violet and ultraviolet light, but only slightly sensitive to green and practically insensitive to the rest of the spectrum. While trying out some factory-made collodion bromide dry plates from England, Vogel was amazed to find that they were more sensitive to green than to blue. He sought the cause and his experiments indicated that this sensitivity was due to a yellow substance in the emulsion, apparently included as an anti-halation agent.

Some painters, notably Cézanne, employ "warm" pigments (red, yellow and orange) to bring features forward towards the viewer, and "cool" ones (blue, violet, and blue-green) to indicate the part of a form that curves away from the picture plane. ; Accommodation : This is an oculomotor cue for depth perception. When we try to focus on far away objects, the ciliary muscles stretch the eye lens, making it thinner, and hence changing the focal length. The kinesthetic sensations of the contracting and relaxing ciliary muscles (intraocular muscles) is sent to the visual cortex where it is used for interpreting distance/depth.

The Stout Creek valley holds the charm of several legends known to locals. There is the story of the nearby Pow Wow Hill, where natives once gathered around a hilltop fire pit. The marshland is said to hide a quicksand pit to which an early 20th-century farmer once lost a horse.

Due to a number of factors, including Rome outlawing the use of Tekhelet by commoners, the source and practice of using a Tekhelet thread in Tzitzit was lost for most Rabbinic Jews. Their Tzitziyot are usually all white. Karaite Jews believe that the importance of Tekhelet is that the color of thread is blue-violet and it may be produced from any source, including synthetic industrial dyes, except impure (a state mostly overlapping unkosher) marine creatures, rather than insist on a specific dye. Therefore, they believe that the rabbinic tradition of relying on a dye from a mollusc is incorrect.

Mannes and Godowsky's experimentation with color photography began in 1917, after seeing the film Our Navy in Prizma Color, which was advertised as a color film. Because of the low quality the boys felt cheated and decided to do something about it. They designed a movie camera and projector each with three lenses covered by orange-red, green and blue-violet filters.US Patent 1,619,949 (filed June 28, 1920, issued March 8, 1927) page 1, lines 25-29 specifies this variant of the standard red, green and blue filter colors, which was also used by the then-current Autochrome process.

Cultivated anemones are nearly always one of the following colors: bluish violet, white, pink, red, and hues in a range between violet and pink. There are no truly blue anemones, despite the frequent use of the label "blue" in marketing to describe blue-violet flowers (flowers that are more violet than blue). Color labelling inaccuracy in marketing is found in treatments of numerous other genera, especially as it concerns the color blue — although some popular garden flowers from the same family are actually blue, such as some selections from Delphinium. One species of anemone, Anemone ranunculoides, is unusual for its yellow flowers.

The Blu-ray Disc uses a blue-violet laser, rather than VMD's red laser, which means Blu-ray can store more information per layer. This format has so far only utilized 1 and 2-layered versions. In January 2007, Toshiba announced development on a triple layer HD DVD (TL51) that would have had a capacity of 51 GB. Hitachi announced a 4 and 6 layer version of Blu-ray as well, capable of 100 GB and 200 GB respectively. A standard 4-layer VMD stored 20 GB, which was comparable to a 1-layered HD DVD (15 GB) and 1-layer Blu-ray Disc (25 GB).

The most distinctive is a pictograph of a man connected to what appears to be a spider by a spiral umbilical cord. The "Spider Man" paint colors vary from red-violet to blue-violet, and were most likely applied using colorful mineral dyes mixed with grease, along with binders from fish roe or animal hooves and skins. However, these pictographs have been fading, due in part to natural wind and water erosion, and in part to tourists applying water to the images to view them better. As of 2009, the "spiderman" image had only two of the "spider legs" visible, the remainder being hidden under lichen and precipitated salts.

Caesium, the heaviest of the alkali metals which can be collected in quantities sufficient for viewing, has a golden hue, whereas the other alkali metals are silver- white. However, relativistic effects are not very significant at Z = 55 for caesium (not far from Z = 47 for silver). The golden colour of caesium comes from the decreasing frequency of light required to excite electrons of the alkali metals as the group is descended. For lithium through rubidium this frequency is in the ultraviolet, but for caesium it enters the blue–violet end of the spectrum; in other words, the plasmonic frequency of the alkali metals becomes lower from lithium to caesium.

Both sexes have brownish/yellow triangular spots on their shoulders. A female Desert Spiny Lizard will lay anywhere from 4 to 24 eggs during the summertime (“Lizards “28. Science Reference Center). A fully grown desert spiny lizard will reach a body length of up to 5.6 inches. Besides their bright colors, the desert spiny lizard changes to darker colors during the winter to allow them to absorb more heat from the sun, and become lighter during the summer to reflect the sun's radiation.

Wurster's blue is the trivial name given to the chemical N,N,N′,N′-tetramethyl-p-phenylenediamine, also known as TMPD. It is an easily oxidised phenylenediamine, which loses two electrons in one-electron oxidation steps; the radical cation is a characteristic blue-violet colour, which gives the compound part of its name. The remaining part of its name comes from its discoverer, the German chemist Casimir Wurster (7 August 1854 – 29 November 1913). The hydrochloride salt finds use as a redox indicator in the oxidase test and is also used in electron transport chain analysis as it is capable of donating electrons to cytochrome c.

The stem has green, inflated, ovate or oblong, spathes (leaves of the flower bud), that sometimes has purple veins. The stems (and the many branches) hold between flowers in early spring,Caledonian Horticultural Society, Edinburgh or late spring and early summer, or May.William Curtis, Samuel Curtis, John Sims, Joseph-Dalton Hooker, William Jackson Hooker (Editors) The flowers are smaller than Iris aphylla, about long. They come in shades of purple, deep purple, blue-violet, light blue or violet. Like other irises, it has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'.

The first pelvic fin ray is always longest in males with the tip of the pelvic fin reaching the anterior base of the anal fin or beyond giving the fin a pointed appearance. The dorsal fin has a red margin followed by a white submargin and black base in the anterior parts and a greyish to clear base in the posterior parts. The caudal fin is clear to pale reddish with a red margin on the upper half followed by a white or iridescent blue part. The anal fin has a red margin on the anterior edge with the rest of fin blue/violet.

The flower of a hybrid butterwort As with almost all carnivorous plants, the flowers of butterworts are held far above the rest of the plant by a long stalk, in order to reduce the probability of trapping potential pollinators. The single, long-lasting flowers are zygomorphic, with two lower lip petals characteristic of the bladderwort family, and a spur extending from the back of the flower. The calyx has five sepals, and the petals are arranged in a two-part lower lip and a three-part upper lip. Most butterwort flowers are blue, violet or white, often suffused with a yellow, greenish or reddish tint.

Mandalas of Influence, 1400 CE Teal: Lan Xang Purple: Lanna Orange: Sukhothai Kingdom Blue Violet: Ayutthaya Kingdom Red: Khmer Empire Yellow: Champa Blue: Dai Viet After the fall of the Khmer Empire in the early 15th century the Dongrek Mountains served as a natural border, leaving the Khmer north of the mountains increasingly under the sphere of influence of Lan Xang. The conquests of Cambodia by Naresuan the Great for Ayutthaya furthered the political and economic isolation from Cambodia proper, leading to a dialect that developed relatively independently from the midpoint of the Middle Khmer period.de Bernon, Olivier.

Like many other colors (orange, rose, and violet are the best-known), indigo gets its name from an object in the natural world—the plant named indigo once used for dyeing cloth (see also Indigo dye). The color electric indigo is a bright and saturated color between the traditional indigo and violet. This is the brightest color indigo that can be approximated on a computer screen; it is a color located between the (primary) blue and the color violet of the RGB color wheel. The web color blue violet or deep indigo is a tone of indigo brighter than pigment indigo, but not as bright as electric indigo.

The superomarginal spines are (more or less) far from the inside edge of plates and they leave on top, on the base of them, a small bare area that it is white if there is a strong spine in the plate (usually in the plates near the disc) or blue-violet if the plate has very small spine or no spine (usually towards the tip of arms). The maximum number of superomarginal plates, observed on each arm, is 48; normally the number is between 29 and 43, depending on the size of the starfish. The inferomarginal spines are long, flat and quite pointed. It is an Astropecten with very variables features and it can have wide or narrow arms.

A set of Tzitzit, four tassels or "fringes" with blue threads produced from a Hexaplex trunculus based dye — tied according to the opinion of the Sefer ha- Chinuch. Tekhelet (; alternate spellings include tekheleth, t'chelet, techelet and techeiles) is a "blue-violet", "blue", or "turquoise" dye highly prized by ancient Mediterranean civilizations and mentioned 49 times in the Hebrew Bible/Tanakh. It was used in the clothing of the High Priest, the tapestries in the Tabernacle, and the tzitzit (fringes) affixed to the corners of one's four-cornered garments, including the tallit. Tekhelet dye was critical for the production of certain articles in the Jerusalem Temple, as well as for the commandment of tzitzit.

Of the 49 or 48 uses in the Masoretic Text, one refers to fringes on cornered garments of the whole nation of Israel (), 44 refer to the priesthood or temple clothes and garments. The remaining 6 in Esther, Jeremiah and Ezekiel are secular uses; such as when Mordechai puts on "blue and white" "royal clothing" in Esther. The color could be used in combination with other colors such as 2 Chronicles where the veil of Solomon's Temple is made of blue-violet (Tekhelet), purple (Hebrew: אַרְגָּמָן Argaman) and scarlet (Biblical Hebrew: שָׁנִי (Shani); Late Biblical, Modern Hebrew: כַּרְמִיל karmiyl). may indicate the source of the shellfish to have been the Aegean region.

Females are usually colored paler than males. On the dorsal side of the body, rock lizards have an occipital stripe composed of a set of black or brown spots and a wide line of the lizard's main color, and dark patterns on the sides of the body. In some species, blue or violet spots with white circles in the center and / or monotonous blue-violet spots at the junction of the abdominal scutes with trunk scales are located on the anterior third of the body. Most types of rock lizards are characterized by a diverse color of the abdominal side of the body, ranging from various shades of pink, red and orange to yellow and green.

The distinction between "warm" and "cool" colors has been important since at least the late 18th century. The difference (as traced by etymologies in the Oxford English Dictionary), seems related to the observed contrast in landscape light, between the "warm" colors associated with daylight or sunset, and the "cool" colors associated with a gray or overcast day. Warm colors are often said to be hues from red through yellow, browns, and tans included; cool colors are often said to be the hues from blue-green through blue violet, most grays included. There is a historical disagreement about the colors that anchor the polarity, but 19th- century sources put the peak contrast between red-orange and greenish-blue.

In the Samaritan tradition, the tallit is a gown worn over their clothes during most holy days, and the tzitzit are considered the 22 "buttons" on the right lapel of the gown, and the corresponding loops on its left lapel. The tzitziyot are always in the same color as the gown, which is usually white. Another version of Samaritan tzitzit is the simple fringes on the sides of the very large white tallit worn by the priests when carrying a Torah scroll. Similarly to most Orthodox rabbinic Jews, the Samaritans hold that the blue- violet tekhelet thread for their tzitziyot was produced from a specific dye, and claim that the tradition for producing it was lost.

Autochrome is an additive color "mosaic screen plate" process. The medium consists of a glass plate coated on one side with a random mosaic of microscopic grains of potato starch dyed red-orange, green, and blue-violet (an unusual but functional variant of the standard red, green, and blue additive colors); the grains of starch act as color filters. Lampblack fills the spaces between grains, and a black-and-white panchromatic silver halide emulsion is coated on top of the filter layer. Unlike ordinary black-and-white plates, the Autochrome was loaded into the camera with the bare glass side facing the lens so that the light passed through the mosaic filter layer before reaching the emulsion.

Chloroplasts are thought to be descended from cyanobacteria that formed endosymbiotic relationships with ancient plant and algal ancestors. Chloroplasts and cyanobacteria contain the blue-green pigment chlorophyll a. Chlorophyll a (as well as its plant and green algal-specific cousin chlorophyll b) absorbs light in the blue-violet and orange/red parts of the spectrum while reflecting and transmitting the green light that we see as the characteristic colour of these organisms. The energy in the red and blue light that these pigments absorb is used by chloroplasts to make energy-rich carbon compounds from carbon dioxide and water by oxygenic photosynthesis, a process that generates molecular oxygen (O2) as a by-product.

The forewings are dark brown, with lemon yellow triangular area, continuous with a yellow tegula, occupying the basal third except for the short costal lenticular spot and a longer, narrower spot along the posterior wing margin, both spots concolorous with the ground color. The apical two thirds of the forewing have an inconspicuous area of white scales near the midlength of the costa and a similar, smaller area slightly more distad. There is a broad transverse band, parallel to distal margin of the yellow area and a small group of scales behind the basal white area. There is a short curved band extending from the distal white area and a submarginal longer straight, iridescent blue violet band parallel to the outer wing margin.

The larval food source for the regal fritillary and all members of the genus Speyeria are violets (Viola spp.) (Selby 2007). The violets are an extremely important component of habitat sustainability for the regal fritillary and there is a correlation between the number of violets present and the number of butterflies found in a given area (Kelly and Debinski 1998). Violet species that the larvae feed on include Viola pedata (bird's-foot violet), V. pedatifida (blue prairie violet), V. papilionacea (common blue violet), V. lanceolata (lance-leafed violet), V. nuttallii (Nuttall's violet) (Kelly and Debinski 1998), V. sagittata (arrowleaf violet), and V. tricolor (Johnny Jumpup) (Selby 2007). These various violet species are associated with the different areas of the regal fritillary's range.

In humans, a lower intensity short wavelength (blue/violet) light appears to be equally effective as a higher intensity of white light. Exposure to monochromatic light at the wavelengths of 460 nm and 550 nm on two control groups yielded results showing decreased sleepiness at 460 nm tested over two groups and a control group. Additionally, in the same study but testing thermoregulation and heart rate researchers found significantly increased heart rate in 460 nm light over the course of a 1.5 hour exposure period. In a study done on the effect of lighting intensity on delta waves, a measure of sleepiness, high levels of lighting (1700 lux) showed lower levels of delta waves measured through an EEG than low levels of lighting (450 lux).

His father was Jewish; his mother was from a mostly Lutheran German family (and was of part Jewish descent through her own grandfather). Mannes and Godowsky's experimentation with color photography began in 1917, after seeing the film Our Navy in Prizma Color, which was advertised as a color film. Because of the low quality the boys felt cheated and decided to do something about it. They designed a movie camera and projector, each with three lenses covered by orange-red, green and blue-violet filters.U.S. Patent 1,619,949 (filed June 28, 1920, issued March 8, 1927) page 1, lines 25-29 specifies this variant of the standard red, green and blue filter colors, which was also used by the then-current Autochrome process.

Daydream Bear a toy-exclusive Care Bear who was originally released as a UK-exclusive plush in the mid-1980s and has since been revived in the 2000s toyline for worldwide release. Daydream Bear shows that daydreams are fun and help inspire people to do great things, but you also have to pay attention to the world around you, as her failure to do so often gets her into funny little accidents. Daydream Bear's appearance changed since her original appearance in the 1980s. In her original appearance, she was pale pink with a pair of rainbow heart balloons and in the early 2000s incarnation, she has blue-violet fur and her tummy symbol is a pink heart shaped ringed planet with stars around it.

Clockwise from the top: red, orange, yellow, chartreuse, green, spring, cyan, azure, blue, violet, magenta, and rose The CMY color model is subtractive in the sense that mixtures of dyes subtract specific wavelengths from the spectral power distribution of the illuminating light which is scattered back into the viewer's eye and is perceived as colored. Mixing of dyes is used to reproduce a gamut of colors, the resultant color from this layer is predicted by multiplying (not subtracting) the absorbance profiles of the dyes. This is essentially opposite to the additive color model, particularly the RGB color model, that applies to lights whose color depends directly on the light. When the intensities for all the components are the same, the result is a shade of gray, lighter, or darker depending on the intensity.

The novels describe Naga as a remarkably beautiful young woman of about 18 or 19 years with a distinguished appearance, long hair (either dark-blue, violet or raven black), and intelligent blue eyes. Tall, well-endowed, and flaunting her sexuality, Naga is in a striking contrast to the diminutive and insecure Lina. She takes pride in being physically intimidating, preferring a menacing and revealing black leather outfit, which is as a keepsake from her mother but Naga also personally enjoys to wear it (though the exaggerated size of her spiked spaulders is so unpractical that Naga has at times jabbed them in her own face when spellcasting). Naga's introduction in the novels describe it as an old-time 'evil sorceress' fashion style that, according to Lina, used to be popular centuries earlier.

These lenticles were precisely shaped to focus light directly onto the emulsion in parallel strips along the length of the film from three color strips in a filter placed over the lens. A record of the color content in black and white was thereby created and could be reconstituted by projecting the film through an identical filter. The three colored stripes (red, green and blue-violet) of the filter had to be precisely oriented parallel to the film length. When an exposure was made, the varying proportion of each color reflected from the subject passed through the filter and was recorded on the film beneath each of the embossed lenticular bands as areas of strips in groups of three, each strip varying in density according to the received color value.

The ASBC and EBC measurements are now identical (both done at the same wavelength and in the same size cuvette) but the scaling is different. A photometer or spectrophotometer is used to measure the attenuation of deep blue (violet) light at 430 nm, as it passes through 1 cm of beer contained in a standard 1 cm by 1 cm cuvette. The absorption is the log of the ratio of the intensity of the light beam entering the sample to the intensity leaving. This difference is multiplied by 12.7 in the SRM system and 25 in the EBC (see below). For example, if the light intensity leaving is one one-hundredth the light intensity entering the ratio is 100, the absorption is 2 and the SRM is 25.4.

Billboard reported that FCC insiders said that CTI's system came in third place, on the basis of color registry and definition. "CTI's sets lacked intensity," it said, "but while its colors were of a hazy blue-violet cast, some engineers believed that it showed potentialities.""Color Show Proves Little; FCC May Split Hue, Freeze", Billboard, March 4, 1950, p. 6. A writer for Popular Science similarly reported that the colors were not true, nor were they in register."You'll Get Color TV Sooner Than You Think", Popular Science, June 1950, p. 108, 110. On August 29, CTI declared in a petition to the FCC that it had invented a "wholly new" color system, which it called "uniplex"."New Color TV Is 'Superior,' Firm Asserts," The Washington Post, Aug 30, 1950, p. B11.

Additive color mixing: adding red to green yields yellow; adding green to blue yields cyan; adding blue to red yields magenta; adding all three primary colors together yields white. Clockwise from the top: red, orange, yellow, chartreuse, green, spring, cyan, azure, blue, violet, magenta, and rose To form a color with RGB, three light beams (one red, one green, and one blue) must be superimposed (for example by emission from a black screen or by reflection from a white screen). Each of the three beams is called a component of that color, and each of them can have an arbitrary intensity, from fully off to fully on, in the mixture. The RGB color model is additive in the sense that the three light beams are added together, and their light spectra add, wavelength for wavelength, to make the final color's spectrum.

As long as photographic materials were usefully sensitive only to blue-green, blue, violet and ultraviolet, three-color photography could never be practical. In 1873 German chemist Hermann Wilhelm Vogel discovered that the addition of small amounts of certain aniline dyes to a photographic emulsion could add sensitivity to colors which the dyes absorbed. He identified dyes which variously sensitized for all the previously ineffective colors except true red, to which only a marginal trace of sensitivity could be added.Vogel, H: "On the sensitiveness of bromide of silver to the so-called chemically inactive colours", Chemical News, December 26, 1873:318–319, copying from The Photographic News, date and page not cited but apparently December 12, 1873 (the latter not known to be available online as of August 6, 2010), in turn translated from Vogel's own publication Photographische Mittheilungen, December, 1873 10(117):233–237.

These laser diodes are mass-produced for the reading and writing of data in Blu-ray drives (although the light emitted by the diodes is not blue, but distinctly violet). In mid-to-late 2011, 405 nm blue-violet laser diode modules with an optical power of 250 mW, based on GaN violet laser diodes made for Blu-ray disc readers, had reached the market from Chinese sources for prices of about US$60 including delivery.In September 2011, GaN diode laser modules capable of operating at 250mW (or 300mW pulse) with a heatsink were offered on eBay in the Industrial Lasers category at around US$60. At the same time, a few higher-powered (120 mW) 404–405 nm "violet" laser pointers have become available that are not based on GaN, but use DPSS frequency-doubler technology from 1-watt 808 nm GaAlAs infrared diode lasers.

In 1895, at the age of 17, Jughashvili's work impressed the noted poet Ilia Chavchavadze, who published five of them in his journal, Iveria, attributed to the pseudonym Soselo. One of these poems, "Morning" (dedicated to Prince Raphael Eristavi), begins: :"The pinkish bud has opened, Rushing to the pale-blue violet And, stirred by a light breeze, The lily of the valley has bent over the grass." Once Jughashvili entered revolutionary politics, and became Stalin, he stopped writing poetry – it took too much time, he told a friend – but in 1907 he still used his prestige as Soselo to obtain information from an admirer needed for a bank robbery. During the Great Purge, he edited a Russian translation of the Knight in the Panther's Skin (by a Georgian intellectual he released from prison for the purpose) and competently translated some of the couplets himself.

A karaite Ṣiṣit with blue threads A Tzitzit (alternatively spelled Ṣiṣit, plural: Tzitziyot or Ṣiṣiyot) is a knotted or braided tassel worn by observant Jews (both Karaite and Rabbinic) on each of the four corners of what is often an outer garment or their Tallit. The Torah commands Israel to make tassels on the corners of their four-cornered garment containing a thread of Tekhelet () and repeats this commandment using the word for "twisted cords" ("Gedilim") instead of "tassels" at . The purpose of the tassels is stated in the Book of Numbers as a visual reminder to the Israelites to remember the commandments given by God. The thread of Tekhelet is a blue- violet or blue thread, which, according to the traditions of Rabbinic Judaism, is to be dyed with a specific kind of dye derived from a mollusc (notably the Hexaplex trunculus sea snail).

Photographic lenses and equipment are designed around the film to be used. Although the earliest photographic materials were sensitive only to the blue-violet end of the spectrum, partially color-corrected achromatic lenses were normally used, so that when the photographer brought the visually brightest yellow rays to a sharp focus, the visually dimmest but photographically most active violet rays would be correctly focused, too. The introduction of orthochromatic emulsions required the whole range of colors from yellow to blue to be brought to an adequate focus. Most plates and films described as orthochromatic or isochromatic were practically insensitive to red, so the correct focus of red light was unimportant; a red window could be used to view the frame numbers on the paper backing of roll film, as any red light which leaked around the backing would not fog the film; and red lighting could be used in darkrooms.

Normalized typical human cone cell responses (S, M, and L types) to monochromatic spectral stimuli The ability of the human eye to distinguish colors is based upon the varying sensitivity of different cells in the retina to light of different wavelengths. Humans are trichromatic—the retina contains three types of color receptor cells, or cones. One type, relatively distinct from the other two, is most responsive to light that is perceived as blue or blue-violet, with wavelengths around 450 nm; cones of this type are sometimes called short-wavelength cones or S cones (or misleadingly, blue cones). The other two types are closely related genetically and chemically: middle-wavelength cones, M cones, or green cones are most sensitive to light perceived as green, with wavelengths around 540 nm, while the long-wavelength cones, L cones, or red cones, are most sensitive to light that is perceived as greenish yellow, with wavelengths around 570 nm.

The 430-nanometer wavelength corresponds to a deep blue (violet) light, and was chosen, as was the multiplier, to make values determined in the SRM system comparable to those determined using the Lovibond system in use at the time the SRM was adopted.Irwin Stone, Miller, M.C. "The Standardization of Methods for the Determination of Color in Beer"ASBC Proceedings 1949 The SRM was adopted in 1950 by the American Society of Brewing Chemists which had recognized the need for an instrument based measurement of color unburdened by the difficulties of the Lovibond system which relies (it is still in use in many industries including brewing malts are often labeled with the Lovibond color of laboratory worts prepared from them) on visual comparison of the sample to tinted glass discs. Beer colors measured in SRM and degrees Lovibond were, as noted above, approximately equal at the time of adoption of the SRM. However, modern analytical methods show that SRM and Lovibond diverge for darker colors.

Charles Hayter published A New Practical Treatise on the Three Primitive Colours Assumed as a Perfect System of Rudimentary Information (London 1826), in which he described how all colors could be obtained from just three. Page from A New Practical Treatise on the Three Primitive Colours Assumed as a Perfect System of Rudimentary Information by Charles Hayter Subsequently, German and English scientists established in the late 19th century that color perception is best described in terms of a different set of primary colors—red, green and blue-violet (RGB)—modeled through the additive mixture of three monochromatic lights. Subsequent research anchored these primary colors in the differing responses to light by three types of color receptors or cones in the retina (trichromacy). On this basis the quantitative description of the color mixture or colorimetry developed in the early 20th century, along with a series of increasingly sophisticated models of color space and color perception, such as the opponent process theory.

Across the same period, industrial chemistry radically expanded the color range of lightfast synthetic pigments, allowing for substantially improved saturation in color mixtures of dyes, paints, and inks. It also created the dyes and chemical processes necessary for color photography. As a result, three-color printing became aesthetically and economically feasible in mass printed media, and the artists' color theory was adapted to primary colors most effective in inks or photographic dyes: cyan, magenta, and yellow (CMY). (In printing, dark colors are supplemented by black ink, known as the CMYK system; in both printing and photography, white is provided by the color of the paper.) These CMY primary colors were reconciled with the RGB primaries, and subtractive color mixing with additive color mixing, by defining the CMY primaries as substances that absorbed only one of the retinal primary colors: cyan absorbs only red (−R+G+B), magenta only green (+R−G+B), and yellow only blue-violet (+R+G−B).

Irwin moved on to landscape projects after developing a stylistic move towards experiential space, projecting what he learned about line, color, and most of all, light onto the built environment. Since 1975 Irwin has conceived of fifty-five site projects. 9 Spaces 9 Trees (1980–3) originally was commissioned in 1980 for the rooftop of the Public Safety Building by the Seattle Arts Commission; it was re-imagined in 2007 and sited on campus at the University of Washington. Irwin's Filigreed Line (1979) made for Wellesley College, Massachusetts, consists of a stainless steel line, running along a ridge of grass near a lake, in which a pattern of leaflike forms is cut. His 1983 work Two Running Violet V Forms, two crossing blue-violet, plastic coated wire fences fixed with high poles, is featured as part of the Stuart Collection of public artwork on the campus of the University of California, San Diego.

Although DVD was initially intended to prevent a format war in fact one did arise between these two formats. It was resolved with both surviving however: DVD-R predominating for stand-alone DVD recorders and players, and (for computers) most DVD devices being engineered as dual format, to be compatible with both. As of 2007 DVD is the de facto standard for pre-recorded movies, and popular storage of data beyond the capacity of CD. With the development of high definition television, and the popularization of broadband and digital storage of movies, a further format development took place, again giving rise to two camps: HD DVD and Blu-ray, based upon a switch from red to blue-violet laser and tighter engineering tolerances. As of 2007 both have significant releases in the pre-recorded movie sector, but they are still only commencing their roll-out for data storage and more general use, and have as yet made little impact on the global market for data storage.

In a possible future, when Nekron launches a new assault on the universe, rapidly recruiting the dead as his agents against the living as his forces claim even more lives, Ganthet triggers a 'last light' protocol that uses the last of his energy to send himself, the rings of six of the seven Corps (Minus a Green Lantern ring) and the last surviving members of the seven Corps to another universe to try and escape Nekron's assault, the various ring-wielders and the rings arriving in the new Star Trek universe. Although the Blue, Violet and Indigo rings find wielders in Pavel Chekov, Nyota Uhura and Leonard McCoy, the Yellow, Red, and Orange rings choose Klingon general Chang, a Gorn leader and a Romulan councillor as their wielders. After the Enterprise crew meet Hal, they rescue Carol and an injured Saint Walker, with McCoy using his Indigo ring to examine Walker's injuries. Although he confirms that Walker will recover, Carol reveals that Nekron was drawn into this new universe along with the rings, Nekron 'manifesting' at the site of Vulcan's destruction.

The slight pinkish tinge caused by colloidal scattering (the effect seen through a glass of water into which a couple of drops of milk have been mixed) is exacerbated, and the use of artificial light—especially fluorescent light—upsets the color rendition of a system which the Lumière Brothers carefully balanced for use with natural daylight. Making modern film or digital copies of Autochromes introduces other problems, because a color system based on red, green, and blue is used to copy an image that exists within the red-orange, green, and blue-violet system, providing further opportunities for color degradation. Vintage reproductions of Autochromes in old books and magazines have often been noticeably hand- adjusted by the photoengravers in an effort to compensate for some of the difficulties of reproduction, and as a result they sometimes look more like hand-colored photographs than "natural color" ones. In short, it is very difficult to form an accurate impression of the appearance of any Autochrome image without seeing the original "in person" and correctly illuminated.

AgF2 is a strong fluorinating and oxidising agent. It is formed as an intermediate in the catalysis of gaseous reactions with fluorine by silver. With fluoride ions, it forms complex ions such as , the blue-violet , and . It is used in the fluorination and preparation of organic perfluorocompounds. This type of reaction can occur in three different ways (here Z refers to any element or group attached to carbon, X is a halogen): # CZ3H + 2 AgF2 → CZ3F + HF + 2 AgF # CZ3X + 2AgF2 → CZ3F + X2 \+ 2 AgF # Z2C=CZ2 \+ 2 AgF2 → Z2CFCFZ2 \+ 2 AgF Similar transformations can also be effected using other high valence metallic fluorides such as CoF3, MnF3, CeF4, and PbF4. is also used in the fluorination of aromatic compounds, although selective monofluorinations are more difficult: :C6H6 \+ 2 AgF2 → C6H5F + 2 AgF + HF oxidises xenon to xenon difluoride in anhydrous HF solutions. :2 AgF2 \+ Xe → 2 AgF + XeF2 It also oxidises carbon monoxide to carbonyl fluoride. :2 AgF2 \+ CO → 2 AgF + COF2 It reacts with water to form oxygen gas: :4 AgF2 \+ 4 H2O → 2 Ag2O + 8 HF + O2 can be used to selectively fluorinate pyridine at the ortho position under mild conditions.
