WebIn a nutshell: The color we percieve an object to have, is the light that was reflected by that object. For example, a (yellow) banana is reflecting light of approximately 580 nm wavelength. It absorbs the rest (or at least the rest of the visible wavelengths). So the color we see is the light that is reflected.
