White is all colors of light mixed, black is
none. Colors are individual wavelengths.
I think gray is some absorption and some reflection of all thewavelengths.
What is brown?
Why do you mix colors of paint (absorbers) together to get brown instead
of gray or black?
In doing a little researching on your inquiry I ran across an absolutely
fascinating website having to do with the physics and seeing of colors.
There is even an interactive routine to show the effects of trichromatic
mixing of colors. You will find the answers to your questions much better
than I could do and it is fun to play with the site.
