Defining D65 White Point Chromaticities for Wide Color Gamut Displays using Different Color Matching Functions

White point chromaticities play an important role in display specifications and calibrations, with the D65 chromaticities widely used in various standards. Such a D65 chromaticities are calculated and specified with the CIE 1931 2° color matching functions (CMFs). Though it is well known that wide color gamut displays always introduce color shifts (i.e., the same D65 chromaticities result in shifted color appearance) and other CMFs were found to have better performance, there is no guidelines about how the D65 white point chromaticities should be shifted. A color matching experiment was carried out in this study, in which 12 displays were used to match the color appearance of a broadband D65 reference. The results can be used as a reference when defining the D65 white point chromaticities using different CMFs.
