color, where like-sized CLUTs
are necessary.
R'G'B'
codes in hicolor systems are directly applied to
the DACs, and are linearly translated into monitor
voltage with no intervening LUT. The response of the
monitor produces luminance proportional to the 2.5-
power of voltage. So, hicolor image coding is perceptu-
ally uniform, comparable to video
R'G'B'
coding.
However, 32 (or even 64) gradations of each compo-
nent are insufficient for photographic-quality images.
