Color theory is quite arcane in many ways. I've been debating for 
years whether to purchase texts on this for my work as a cartographer
and graphics designer. It is one of those areas of knowledge where
art, science, humanities & technology merge and and produce something
that is ambiguously tangible. For example, in my work with old time
4-color (pre-Postscript?!) printing, I've met a number of older
pressmen who were seriously "afflicted" with red/green color blindness
and were able to produce excellently proofed work. They would get
their results by using the poundage of the inks used. Believe it or
not.
