WebThus the CIE 1931 Standard Observer function is also known as the CIE 1931 2° Standard Observer. A more modern but less-used alternative is the CIE 1964 10° Standard Observer, which is derived from the work of Stiles and Burch, [7] and Speranskaya. [8] WebCIE defined a color-mapping function called the standard (colorimetric) observer, representing an average human's chromatic response of the human fovea (the area of the retina with the highest concentration of cones) within a 2° arc. The three spectral sensitivity curves are labeled X, Y, and Z.
