D65 is not the same as 6500K!
It is important to understand what the first “C” in CCT stands for – correlated color temperature. A single CCT value, including 6500K, can have many green/magenta hue variations that all correlate to a color temperature of 6500K.
Most manufacturers will have an internal
ANSI separately developed its standard for 6500K using the xy chromaticity coordinates of (0.313, 0.337), and most manufacturers will strive to hit this color point as their target color point. How far off is this from the D65 xy chromaticity coordinates of (0.31271, 0.32902)?
