This is something that puzzles me ….. I understand sound theory pretty well… and we know sound is vibrating air ….for pure tones the air pressures varies as a sine wave…. and, color is a vibrating electromagnetic field ……again with pure colors represented by sine waves …..
Here is what I don’t understand …how is it that you can, as I understand, choose 3 primary colors….. and mix them to get any color at all ????? It seems quite unlikely …. for example…. when three sinewaves of different frequencies are added, the result is not a pure sinewave at a different frequency …. suggesting to me that you can’t generate the pure colors, much less all the colors.
And, no one would suggest that you can take 3 pure (sound) tones and generate all the pure tones, much less all the sounds ….. so, what is it about light that is different from sound .. ?????
Is there any easy explanation ???? Or a link I could check, to relieve my bafflement????
