Template:Color temperature white points
A list of standardized illuminants, their CIE chromaticity coordinates (x,y) of a perfectly reflecting (or transmitting) diffuser, and their correlated color temperatures (CCTs) are given below. 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.
