Color At the resonant frequencies where the amplitudes of oscillation are large, light is absorbed. But at frequencies  below and above the resonant frequencies, light is re- emitted (reflected) An object can only reflect frequencies that are present in the illuminating light. A red piece of glass appears red because it absorbs all the colors that compose white light, except red, which it  transmits. The energy of the absorbed frequencies increase the kinetic energy of the molecules and the glass is warmed. Any of the three additive primaries can be produced by a combination of any two of cyan, magenta, or yellow  pigments. The latter three are called  subtractive primary colors. A color plus its opposite ( complementary)  produce white. The tinier the particle, the higher the frequency of light it will scatter. Of the visible frequencies violet light is scattered the most, followed by blue, green, yellow, orange, and red.
