D65


Spectral power distribution of the D65 white point

'D65' is one of the standard illuminants (or white points) defined by the International Commission on Illumination (CIE). It is one of a series of illuminants called ''D'' series that try to portray standard illuminanting conditions at open air in different parts of the world.
'D65' corresponds roughly to a midday sun in Western / Northern Europe, hence it is considered and called as well a daylight illumination. As any standard illuminant is just a table of colorimetric average data, any light source which correlates to that spectral curve can be labelled as being a D65 light source.
The CIE 1931 chromaticity coordinates of D65 are ''x''=0.31271, y=0.32902. The CIE 1964 chromaticity coordinates are ''x''=0.31382, ''y''=0.33100. These correspond to a correlated color temperature of 6500 K.
