A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision.. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
Special-purpose color spaces. The rg chromaticity space is used in computer vision applications, and shows the color of light (red, yellow, green, etc.), but not its intensity (dark, bright). LMS color space (long, medium, short), a perceptual color space based on the response functions of the cones in the retina of the eye.
In common English usage, purple is a range of hues of color occurring between red and blue. [1] However, the meaning of the term purple is not well defined. There is confusion about the meaning of the terms purple and violet even among native speakers of English. [2] Many native speakers of English in the United States refer to the blue ...
Main article: RGB color model. Media that transmit light (such as television) use additive colormixing with primary colorsof red, green, and blue, each of which stimulates one of the three types of the eye's color receptors with as little stimulation as possible of the other two. This is called "RGB" color space.
The CIELAB color space, also referred to as L*a*b*, is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. [a] It expresses color as three values: L* for perceptual lightness and a* and b* for the four unique colors of human vision: red, green, blue and yellow. CIELAB was intended as a perceptually ...
RGB color spaces are well-suited to describing the electronic display of color, such as computer monitors and color television. These devices often reproduce colours using an array of red, green, and blue phosphors agitated by a cathode ray tube (CRT), or an array of red, green, and blue LCDs lit by a backlight, and are therefore naturally ...
In Wikipedia, the coordinates are presented as four numbers separated by commas, as in this example for the color orange: (0, 35, 100, 0) The coordinates within the parenthesis provide, from left-to-right, the relative values of cyan, magenta, yellow, and key. The number in each position ranges from 0 (no pigment used) to 100 (maximum = 100% ...
Fuchsia ( / ˈfjuːʃə /, FEW-shə) is a vivid pinkish-purplish- red color, [1] named after the color of the flower of the fuchsia plant, which was named by a French botanist, Charles Plumier, after the 16th-century German botanist Leonhart Fuchs . The color fuchsia was introduced as the color of a new aniline dye called fuchsine, patented in ...
