Again, 5000K is a LOT of differing colors. Which do you want? If you
look at the lines of correlated color temp on a CIE chromaticity
diagrams, those colors range widely from a magenta to green axis.
This is one reason why the CIE defined the Standard Illuminants.These
illuminants are defined spectrally meaning a certain amount of energy
at each wavelength across the spectrum. This is an exact and non
ambiguous description of color. D50 is an exact color, it is not a
range of colors. A color whose CCT is 5000K is not unique as there are
infinitely many different xyY and SPDs that share it.
