Color When atoms or compounds absorb light of the proper frequency, their electrons are excited to higher energy levels. Colored compounds absorb visible (colored) light and this absorption is responsible for their color. Our eyes perceive a mixture of all of the colors, as in the proportions in sunlight, as white light. The following figure shows how the mixture of colors that the eye perceives as white light is separated as the light passes through a prism. As shown in the next figure, an object is seen as black if it absorbs all colors of white light. 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. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light. It reflects yellow light and we see it as yellow. The eye also uses complementary colors in color vision. When a color is removed from white light we see the complementary color. The following table shows the colors seen when a complementary color is removed (for example, by a color filter).
