What is reflected back to the eye appears as the color of the object. Grass looks green, for example, because the pigments in it absorb all the wavelengths of sunlight except green, which is reflected back to us. When all wavelengths of light are absorbed, an object looks black. This would happen, for instance, if you were to shine only yellow or red light on a blue towel. Since the towers pigment reflects only blue and there is no blue in yellow or red light, the towel would absorb all the yellow or red light and appear black. Rather than a color, therefore, black is the absence of color.
