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.
The CIE defines illuminant A in these terms: CIE standard illuminant A is intended to represent typical, domestic, tungsten-filament lighting.
The CIE 1931 colour space chromaticity diagram with wavelengths in nanometers.The colors depicted depend on the color space of the device on which the image is viewed.. The International Commission on Illumination (usually abbreviated CIE for its French name Commission internationale de l'éclairage) is the international authority on light, illumination, colour, and colour spaces.
Axis Bank Limited, formerly known as UTI Bank (1993–2007), is an Indian multinational banking and financial services company headquartered in Mumbai, Maharashtra. [8] It is India's third largest private sector bank by assets and fourth largest by market capitalisation.
The solid curve with dots on it, through the middle, is the Planckian locus, with the dots corresponding to a few select black-body temperatures that are indicated just above the x-axis. Since the human eye has three types of color sensors that respond to different ranges of wavelengths, a full plot of all visible colors is a three-dimensional ...
CIELUV is an Adams chromatic valence color space and is an update of the CIE 1964 (U*, V*, W*) color space (CIEUVW). The differences include a slightly modified lightness scale and a modified uniform chromaticity scale, in which one of the coordinates, v′, is 1.5 times as large as v in its 1960 predecessor.
English: The visible gamut plotted within the CIELAB color space. a and b are the horizontal axes. L is the vertical axis. L is the vertical axis. Uses D65 whitepoint.
The asterisks in the exponent indicates that the variable represent a more perceptually uniform color space than its predecessor (compare with CIELAB). Günter Wyszecki invented the UVW color space in order to be able to calculate color differences without having to hold the luminance constant.
