  2. CIELAB color space - Wikipedia

    en.wikipedia.org/wiki/CIELAB_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 produces a color space that is more perceptually linear than other color spaces. Perceptually linear means that a change of the same amount in a color value should produce a change of about the same visual importance. CIELAB has almost entirely replaced an alternative related Lab color space called “Hunter Lab”. This space is ...

    en.wikipedia.org/wiki/Hunter_Lab

    Hunter Lab (also known as Hunter L,a,b) is a color space defined in 1948 [1] [2] by Richard S. Hunter. It was designed to be computed via simple formulas from the CIEXYZ space, but to be more perceptually uniform.

  5. Color space - Wikipedia

    en.wikipedia.org/wiki/Color_space

    A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary color system with no connection to any globally understood system of ...

    en.wikipedia.org/wiki/CIE_1931_color_space

    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).

  7. Oklab color space - Wikipedia

    en.wikipedia.org/wiki/Oklab_color_space

    The Oklab color space is a uniform color space for device independent color designed to improve perceptual uniformity, hue and lightness prediction, color blending, [a] and usability while ensuring numerical stability and ease of implementation. [1]

  9. Pigment - Wikipedia

    en.wikipedia.org/wiki/Pigment

    Color spaces used to represent colors numerically must specify their light source. Lab color measurements, unless otherwise noted, assume that the measurement was recorded under a D65 light source, or "Daylight 6500 K", which is roughly the color temperature of sunlight. Sunlight encounters Rosco R80 "Primary Blue" pigment.
