It goes from less-something to more-something as frequency but more-something to less-something as wavelength. "colour" is a mix of power at each frequency, and everyone has different retinas, different optical cortices, and different cultural contexts.

Distinctly we see the difference of the colors, but where exactly does the one first blendingly enter into the other? So with sanity and insanity." -- Herman Melville, Billy Budd What I love about this quote is that violet and orange are so far apart in the rainbow.
