I don't know about waves but my understanding is that all colors come
from the mixing of the three basic colors, or is it four? When you mix frequencies I
would imagine you could arrive at all possible frequencies. I think
you should drop the idea of waves with respect to frequency. If you
observe a rainbow how many basic colors are there in the mix!

The visible spectrum does not include "basic colors" It pretty much has
all of them. Well, not Magenta. Is magenta a color?

And when you talk "basic, are you talking Cyan, Magenta, Yellow, or Red,
Green, Blue. It makes a difference.


In a
projector isn't there just three filters required for a movie in
color? One thing you have to get into your mind is the idea of basic
temperature and mass without energy.

That would be a black body radiator at absolute 0.
