Are white and black colours?

Who said white and black inst a color? Science? I don't give a flying rat what anyone says, White and black are colors.
You wouldn't go into a paint shop asking for light would you. Look here to the left. What do you see? White to black value chart. these are colors, grey too. 'what colour would you paint your bathroom? White? Yes.

Yes it makes sense to say that black is an absence of color and light  but pigmented it is a color.
Its the same with white, yes the sun has white light which is why we get rainbows when it rains because the colors split blah blah blah whatever.

Anyways, to do with light when you mix all colors you get white, but with pigments, you mix all colors and you  get what? i dunno, grey? black? certainly not white though O__o

I refuse to open my mind to this controversial subject. In this backwards world I'm not a science person therefore 'logic' is nonsense to me and nonsense is logic. I'm getting too carried away here LOL
