Color Theory

This is my first exposure to the science of color that I never knew existed.  It seems this extremely subjective facet of human life actually has quite a bit of theory and fact behind it.  As I was reading, I started likening this theoretical approach of color to that of the theoretical approach to music.  Ultimately it is up to us to take in a stimuli and decide whether or not it is appealing.  However, through what I can only assume is huge amounts of research, we find that we can tip the scales in our favor with a bit of logic.  The part about triadic and tetradic color schemes reminded me of chord charts for guitar.  It basically shows we have boiled things down to a simple 'this works well with that' system, like we have more or less solved the issue of what colors to use.  It is crazy how well people can come to understand something as seemingly infinite as color combinations.
