question about colors

My friends and I have be quarreling about which of these is correct:

BLACK is the absence of color

WHITE is the absence of color

BLACK is the product of all colors

WHITE produces all colors.

I think what the difference is whether you are talking about light or just artist colors…any idea how to resolve this. I know this is probably easy for you but I need a surefire answer to shut them all up.

i realized i shoulda put this in GD so i will…closed
