Color systems RGB and CIE XYZ A vector space for colors Because of the trichromatic nature of vision, a color can be perfectly defined by a set of only three numbers, which can be thought of as the coordinates of a vector in a 3-D vector space.

The green function in RGB is not that different from the luminous efficiency  According to this document, Y in YUV is same as Y in CIE XYZ space. However, L in CIE LAB space has a nonlinear relation with Y. You can  toRGB convert a CIE color to an SRGB color. This function uses toRGBMatrix convert an XYZ color to an SRGB color using a provided matrix. toLAB :: CIEXYZ   The CIE-XYZ Color Coordinate System. In this system, the XYZ Tristimulus values can describe any visible color.

It is also known as the CIE XYZ color space or the CIE 1931 XYZ color space. The CIE 1931 RGB color space and CIE 1931 XYZ color space were created by the International Commission on Illumination (CIE) in 1931. They resulted from a series of experiments done in the late 1920s by William David Wright and John Guild. CIE 1931 Color Space or CIE XYZ In 1931, the International Commission on Illumination or CIE, which is the abbreviation for its French name, Commission internationale de l'éclairage, established the first system for scientifically defining light colors or additive colors .

The non-linear relations for L*, a*, and b* are intended to mimic the logarithmic response of the eye, coloring information is referred to the color of the white point of the system. CIE XYZ are derived from that to be just non-negative, and so that the Luminance is defined by only Y. This is more convenient for color science. ACES RGB is another perfect conversion, convenient for digital film production. The CIE XYZ color space encompasses all color sensations that are visible to a person with average eyesight.
