Impossible Colors
Impossible colors are colors that do not appear in ordinary visual functioning. Different color theories suggest different hypothetical colors that humans are incapable of perceiving for one reason or another, and fictional colors are routinely created in popular culture. While some such colors have no basis in reality, phenomena such as cone cell fatigue enable colors to be perceived in certain circumstances that would not be otherwise. Opponent process The color opponent process is a color theory that states that the human visual system interprets information about color by processing signals from cone and rod cells in an antagonistic manner. The three types of cone cells have some overlap in the wavelengths of light to which they respond, so it is more efficient for the visual system to record differences between the responses of cones, rather than each type of cone's individual response. The opponent color theory suggests that there are three opponent channels: * Red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reddish
Reddish is an area in Metropolitan Borough of Stockport, Greater Manchester, England. south-east of Manchester city centre. At the 2011 Census, the population was 28,052. Historically part of Lancashire, Reddish grew rapidly in the Industrial Revolution and still retains landmarks from that period, such as Houldsworth Mill, a former textile mill. Reddish Vale is a country park. History Toponymy Reddish is recorded as Redich (1205, 1212), Redych, Radich (1226), Radish, Rediche (1262), Redditch (1381), Redwyche, Radishe and Reddishe (16th century).Farrer and Brownbillpp. 326–9Booker, p. 197. The name either means "reedy ditch" ( OE ''hrēod-dīc'') or "red ditch" (OE ''rēad-dīc''). Ekwall (1922) allows either form, stating "red" is less probable; Mills (1991) and Arrowsmith (1997) only give the "reed" option.Arrowsmith, p. 23. The ditch referred to is possibly the Nico Ditch, an earthwork of uncertain origin bordering Reddish, Manchester and Denton. Folklore has it ...

Additive Color
Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. Modern formulations of Grassmann's laws describe the additivity in the color perception of light mixtures in terms of algebraic equations. Additive color predicts perception and not any sort of change in the photons of light themselves. These predictions are only applicable in the limited scope of color matching experiments where viewers match small patches of uniform color isolated against a grey or black background. Additive color models are applied in the design and testing of electronic displays that are used to render realistic images containing diverse sets of color using phosphors that emit light of a limited set of primary colors. Examination with a sufficiently powerful magnifying lens will reveal that each pixel in CRT, L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Complementary Colors
Complementary colors are pairs of colors which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale color like white or black. When placed next to each other, they create the strongest contrast for those two colors. Complementary colors may also be called "opposite colors". Which pairs of colors are considered complementary depends on the color theory one uses: *Modern color theory uses either the RGB additive color model or the CMY subtractive color model, and in these, the complementary pairs are red–cyan, green– magenta, and blue–yellow. *In the traditional RYB color model, the complementary color pairs are red–green, yellow–purple, and blue– orange. *Opponent process theory suggests that the most contrasting color pairs are red–green and blue–yellow. *The black-white color pair is common to all the above theories. In different color models Traditional color model The traditional color wheel model dates to the 18th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afterimage
AfterImage is a Filipino rock band formed in 1986, best known for their songs "Habang May Buhay", "Next in Line", and "Mangarap Ka". They disbanded in 1997 and became active again in 2008 after they reunited and released their fourth studio album. After disbanding in 1997, Wency Cornejo, the band's vocalist, pursued a solo career. In January 1992, the band signed with Dyna Records, The band's first album, entitled ''Touch the Sun'', was released in July 1992. Among the eight songs that the album contained, four were released as singles: "Next in Line", "Bai (Sa Langit ang Ating Tagpuan)", "Only You", and "Pagtawid". The title of the album, which was the concluding part of the lyric to "Next in Line", was said to have just been a spontaneous utter of phrase which Cornejo made during the recording session for the said song. History The band was composed of five members: Bobit Uson on bass guitar, Chuck Isidro on lead guitar, Rogie Callejo on drums, Arnold Cabalza on keyboards and ...

Opponent Process
The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels, each comprising an opposing color pair: red versus green, blue versus yellow, and black versus white (luminance). The theory was first proposed in 1892 by the German physiologist Ewald Hering. Color theory Complementary colors When staring at a bright color for awhile (e.g. red), then looking away at a white field, an afterimage is perceived, such that the original color will evoke its complementary color (green, in the case of red input). When complementary colors are combined or mixed, they "cancel each other out" and become neutral (white or gray). That is, complementary colors are never perceived as a mixture; there is no "greenish red" or "yellowish blue", despite claims to the contrary. The strongest color con ...

Color Gamut
In color reproduction, including computer graphics and photography, the gamut, or color gamut , is a certain ''complete subset'' of colors. The most common usage refers to the subset of colors which can be accurately represented in a given circumstance, such as within a given color space or by a certain output device. Another sense, less frequently used but still correct, refers to the complete set of colors found within an image at a given time. In this context, digitizing a photograph, converting a digitized image to a different color space, or outputting it to a given medium using a certain output device generally alters its gamut, in the sense that some of the colors in the original are lost in the process. Introduction The term ''gamut'' was adopted from the field of music, where in middle age Latin "gamut" meant the entire range of musical notes of which musical melodies are composed; Shakespeare's use of the term in ''The Taming of the Shrew'' is sometimes attributed to ...

Color Saturation
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity. As defined formally by the International Commission on Illumination (CIE) they respectively describe three different aspects of chromatic intensity, but the terms are often used loosely and interchangeably in contexts where these aspects are not clearly distinguished. The precise meanings of the terms vary by what other functions they are dependent on. * Colorfulness is the "attribute of a visual perception according to which the perceived color of an area appears to be more or less chromatic"., page 87. The colorfulness evoked by an object depends not only on its spectral reflectance but also on the strength of the illumination, and increases with the latter unless the brightness is very high ( Hunt effect). * Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarly illuminated area that appears white or highly transmitting".

Trichromatic Theory
Trichromacy or trichromatism is the possessing of three independent channels for conveying color information, derived from the three different types of cone cells in the eye. Organisms with trichromacy are called trichromats. The normal explanation of trichromacy is that the organism's retina contains three types of color receptors (called cone cells in vertebrates) with different absorption spectra. In actuality the number of such receptor types may be greater than three, since different types may be active at different light intensities. In vertebrates with three types of cone cells, at low light intensities the rod cells may contribute to color vision. Humans and other animals that are trichromats Humans and some other mammals have evolved trichromacy based partly on pigments inherited from early vertebrates. In fish and birds, for example, four pigments are used for vision. These extra cone receptor visual pigments detect energy of other wavelengths, sometimes including ...
