we perceive color
White light really isn't white,
it is composed of many different colors. When you see color all you are
seeing is reflections of certain parts of the white light, while the rest
of the light is absorbed by the object.
The density and complexity of
an object determines the different amounts and colors of light that the
object absorbs and which it reflects.
If the object is black, then it
absorbs all of the light, if it is white, then it reflects all of the light.
The primary light colors are red,
blue, and green. All of the colors are comprised of different combinations
of these three colors.
