CIELAB (any white point) is a supported color space in TIFF image files. [17] CIELAB (any white point) is available in PDF documents, where it is called the "Lab color space". [18] [19] CIELAB is an option in Digital Color Meter on macOS described as "L*a*b*". CIELAB is available in the RawTherapee photo editor, where it is called the "Lab ...
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 ...
There are also likely to be rounding errors, especially if the popular range of only 256 distinct values per component (8-bit color) is used. One part of the definition of an absolute color space is the viewing conditions. The same color, viewed under different natural or artificial lighting conditions, will look different. Those involved ...
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.
A color space maps a range of physically produced colors from mixed light, pigments, etc. to an objective description of color sensations registered in the human eye, typically in terms of tristimulus values, but not usually in the LMS color space defined by the spectral sensitivities of the cone cells.
Color Space and Its Divisions: Color Order from Antiquity to the present. New York: Wiley. ISBN 978-0-471-32670-0. This book only briefly mentions HSL and HSV, but is a comprehensive description of color order systems through history. Levkowitz, Haim; Herman, Gabor T. (1993).

As most definitions of color difference are distances within a color space, the standard means of determining distances is the Euclidean distance.If one presently has an RGB (red, green, blue) tuple and wishes to find the color difference, computationally one of the easiest is to consider R, G, B linear dimensions defining the color space.
In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value , and chroma (color intensity). It was created by Albert H. Munsell in the first decade of the 20th century and adopted by the United States Department of Agriculture (USDA) as the official color system ...
