@123 Thanks for the heads-up about that!
And while I don’t at all want to take away from @cloak’s commendable efforts there, it seems that that post offers these color-conversion functions, and of them, it doesn’t appear that there are currently functions for converting from those color systems to Kelvin (other than colour_mireds_to_kelvin
)?:
cct_to_xy
xyY_to_XYZ
XYZ_to_sRGB
gamma_correct_sRGB
colour_temperature_to_rgb
rgb_to_hs
colour_mireds_to_kelvin
