Not an exact correlation. Whereas the piano encompasses 7+ octaves and the ear more than that (for some of us), the visible spectrum is only about one octave. I think it would work for color names to repeat every octave the same as note and solfege names do. And instead of using the resistor/capacitor color code, I think it would make sense to use the colors of the rainbow: red-orange-yellow-green-blue-violet-________. Hmmmmmm. Maybe the visible spectrum is less than an octave. You said 7700 - 4000 angstrom units. That's less than a 2:1 ratio so maybe we miss one of the colors? -- Thomas A. Cole RPT Santa Cruz, CA
