The Short Answer

Colors are a response your brain makes to picking up certain wavelengths of electromagnetic radiation striking receptor cells in your brain. When this happens, those cells send signals to your brain, and your brain creates the image. Certain combinations of stimulation on those cells cause your brain to generate different colors, to help further discriminate, because this is a beneficial evolutionary adaptation (harder for things to blend together). Color itself is not a property of light or anything. Rather, a product of your brain interpreting it.
