Scope

This standard specifies the color matching functions used in colorimetry. Two color matching functions are specified. a) CIE 1931 Standard Color Observer Color Matching Function This color matching function describes the color matching characteristics of observers with normal color vision under adapted bright vision, with a field of view of approximately 1° to 4°. b) CIE 1964 Supplementary Standard Color Observer Color Matching Function This color matching function describes the color matching characteristics of observers with normal color vision under sufficiently high bright vision, and in cases where the spectral power distribution causes cone photoreceptors in the retina not to participate, in a field of view greater than 4°.
