![]() The CIE 1931 color spaces are still widely used, as is the 1976 CIELUV color space. The experimental results were combined into the specification of the CIE RGB color space, from which the CIE XYZ color space was derived. They resulted from a series of experiments done in the late 1920s by William David Wright using ten observers and John Guild using seven observers. The CIE 1931 RGB color space and CIE 1931 XYZ color space were created by the International Commission on Illumination (CIE) in 1931. ![]() The system was designed in 1931 by the "Commission Internationale de l'éclairage", known in English as the International Commission on Illumination. The mathematical relationships that define these color spaces are essential tools for color management, important when dealing with color inks, illuminated displays, and recording devices such as digital cameras. The CIE 1931 color spaces are the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiologically perceived colors in human color vision. CIE RGB color cube (image encoded with an ICC profile) The color matching functions are the amounts of primaries needed to match the monochromatic test color at the wavelength shown on the horizontal scale. ![]() The CIE 1931 RGB color matching functions.
