A couple of days ago you said that the problem was that
"Actual atoms, the kind that the world is composed of, have no color. They are far too small. An object's color is determined by the wave length of the visible light that it reflects most strongly. But atoms do not reflect light at all."
So now you're saying colour is not determined by wavelength?
Actually, color is *not* determined by wavelength. Color is a neurological/psychological phenomenon, primarily the product of a certain small processing center in the brain. Check out a book called "An Anthropologist on Mars," a collection of essays by a neurosurgeon about patients he has studied, including a professional artist who suffered an injury to that particular processing center and no longer saw color correctly. There seems to be some indication that our perception of color is partly learned from those around us. David gnome@hawaii.rr.com
