You could search for it by yourself. It depends on the color spaces
of CMY/CMYK/RGB, i.e., the ranges of each component, gamma
corrections, etc., but with all RGBCMYK ranging from 0 to 255, I think
you can do
# CMY to RGB
R=$((~C&0xFF))
G=$((~M&0xFF))
B=$((~Y&0xFF))
# CMYK to RGB
M=$((~K&0xFF))
R=$(((~C&0xFF)*M/255))
G=$(((~M&0xFF)*M/255))
B=$(((~Y&0xFF)*M/255))
