CIE standard observer: these are the color matching functions defined by CIE and used to represent "average" human color perception. CIE1931 is the 2 degree standard observer more useful for describing color perception over very small areas or at distance. CIE1964 is the 10 degree standard observer, used for most industrial color matching applications. |
