Colorimetry - CIE standard colorimetric observers Ingestion-build-228203 well-defined interfaces and measuring techniques1 Scope This document specifies colour matching functions for use in colorimetry. Two sets of colour matching functions are specified. a) Colour matching functions for the CIE 1931 standard colorimetric observer. This set of colour matching functions is representative of the colour matching properties of observers with normal colour vision for visual field sizes of angular subtense from about 1 to about 4, for vision at photopic levels of adaptation.
