Red, Green, and Blue are the additive primary colors of light. Together, in equal proportions, they add up to white.

Yellow, Magenta, and Cyan (with 'K' (or black) added for Kontrast) are used in process color printing. Yellow, Magenta, and Cyan dyes are also used in silver halide based photographic films and papers. The subtractive secondaries subtract red or green or blue from the white light reflected from paper. Both film and paper make negative images, so two negatives together equal a positive image...

Yes, I have noticed that the additive and subtractive systems are opposite and I am wondering how or why this is. I'm thinking that there must have been some kind of planning here and reasoning that this was done.
