"Sunlight, as Sir Isaac Newton discovered, is a combination of the seven colors that compose the spectrum. An object is red because it is so constituted that it reflects the red rays of a beam of sunlight but absorbs all others ... a lily is white because it reflects all the rays ... a buttercup is yellow because it reflects only the yellow rays, absorbing all others ... an object is black because it absorbs all the colors of the spectrum."
