CIE 1931 color space - Wikipedia
The experimental results were combined, creating the CIE RGB color space. The CIE XYZ color space was derived from CIE RGB in an effort to simplify the math. The CIE 1931 XYZ color space is still widely used, even though it is not perceptually uniform in relation to human vision.
CIELAB color space - Wikipedia
The "CIELCh" or "CIEHLC" space is a color space based on CIELAB, which uses the polar coordinates C* (chroma, relative saturation) and h° (hue angle, angle of the hue in the CIELAB color wheel) instead of the Cartesian coordinates a* …
List of color spaces and their uses - Wikipedia
There have been many attempts at building such a color space. As human vision has three components, the space is necessarily 3D; it is generally assigned such that one is the lightness and the other two the chroma. A uniform color space is useful for a wide range of tasks.
What is the CIE Color Space? What’s the difference between CIE …
To quantify any color as a coordinate on this color space, the CIE specifies mathematical “color matching functions.” The functions are derived based on the tristimulus values (X, Y, and Z) at any point in the color space.
1931, CIE adopted these results as the standard-ized RGB color matching functions. Then still in 1931, for practical convenience, CIE transformed the RGB color matching functions to a new set of primaries, XYZ, to eliminate negative values and with the G function to be equal to the 1924 CIE spectral luminous efficiency func-tion, V(λ).

Sep 10, 2016 · They mostly commonly refer to the sRGB color space, created by Microsoft in 1996. sRGB, and another popular web color space Adobe RGB are each defined by their own three primary colors.
CIE Color System - HyperPhysics
The diagram at left represents the the mapping of human color perception in terms of two CIE parameters x and y. The spectral colors are distributed around the edge of the "color space" as shown, and that outline includes all of the perceived hues and provides a framework for investigating color.
CIE's three RGB primary color stimuli. It was sometimes necessary to mix the color sample with one of the three primary colors to reach equivalence with the mixture from the two remaining primary colors. This means that certain colors can only be mixed from the three primary colors if one primary color contributes a “negative portion”. For
CIE Fundamentals for Color Measurements | NIST - National …
Sep 30, 2000 · The paper reviews the measurement of object colors introducing CIE standard illuminants and the CIE terminology for color and reflectance measurements, then the measurement of light-source colors (including displays) with calculation of correlated color temperature and color rendering indices.
CIE Lab Colour Space can be used to measure colour quantitatively. Since Isaac Newton discovered that white light contained all the colours of the spectrum in 1666 (Beretta, G. pg. 17), people have been trying to adequately describe colour in a quantifiable and reproducible way.
