Colored compounds absorb visible (colored) light and this absorption is responsible for their color. A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb.
What two colors make white?
If you mix red, green, and blue light, you get white light. This is additive color. As more colors are added, the result becomes lighter, heading towards white.
Which light can be seen by our eyes?

On one end of the spectrum there is infrared light, which, while too red for humans to see, is all around us and even emitted from our bodies.
