The CIE positions D65 as the standard daylight illuminant: [D65] is intended to represent average daylight and has a correlated colour temperature of approximately 6500 K. CIE standard illuminant D65 should be used in all colorimetric calculations requiring representative daylight, unless there are specific reasons for using a different illuminant.
The CIE chromaticity coordinates are given for both the 2 degree field of view (1931) and the 10 degree field of view (1964). [1] The color swatches represent the color of each white point, automatically calculated by Wikipedia using the Color temperature template.
PDF version of the chart. The colors of the chart were described by McCamy et al. with colorimetric measurements using the CIE 1931 2° standard observer and Illuminant C, and also in terms of the Munsell color system. Using measured reflectance spectra, it is possible to derive CIELAB coordinates for Illuminants D 65 and D 50 and coordinates ...

An illuminant is characterized by its relative spectral power distribution (SPD). The white point of an illuminant is the chromaticity of a white object under the illuminant, and can be specified by chromaticity coordinates, such as the x, y coordinates on the CIE 1931 chromaticity diagram (hence the use of the relative SPD and not the absolute SPD, because the white point is only related to ...
The y G coordinate too is the same, while x G is halfway between EBU Tech 3213's x G and SMPTE C's x G. The resulting BT.709 color space is almost identical to that of the BT.601-6 used by PAL and NTSC, and covers 35.9% of it. [19] It also covers 33.24% of the CIE 1976 u’v’ space [20] [21] and 33.5% of the CIE 1931 x y diagram. [21]
