How do color meters take into account the iso-effect line in the Plankian locus plot of color temp on a map of colors.
As you can see there are a lot of different chromaticities represented at each iso temp line perpendicular to the temperature axis. For example, it appears that a temperature of 10,000 degrees K could be seen in a color varying from green through cyan and blue to magenta! So do the meters actually isolate amber-blue from magenta-cyan? Or is the magenta cyan also used in determining color temp? Also are there meters that give the relative proprtions of cyan and blue in the light too to qualify the color temperature beyond amber to blue?
