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.
Hunter Lab (also known as Hunter L,a,b) is a color space defined in 1948 [24] [25] by Richard S. Hunter. It was designed to be computed via simple formulas from the CIEXYZ space, but to be more perceptually uniform. Hunter named his coordinates L, a and b.
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 ...
Richard Sewall Hunter (1909–1991) was a pioneering American color scientist and founder of Hunter Associates Laboratory (HunterLab). [1] [2] He is best known as the inventor in 1942 of the Hunter L,a,b color measurement system the precursor to the CIELAB color space. [3] [4] Hunter was awarded the David Richardson Medal in 1971 by the Optical ...
Adams chromatic valence color spaces are a class of color spaces suggested by Elliot Quincy Adams. [1] Two important Adams chromatic valence spaces are CIELUV and Hunter Lab . Chromatic value/valence spaces are notable for incorporating the opponent process model and the empirically-determined 2 + 1 ⁄ 2 factor in the red/green vs. blue/yellow ...
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).

Colorimetry is "the science and technology used to quantify and describe physically the human color perception". [1] It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.
