When a light beam hits an object, such as tree leaves or
an apple, the color of the object affects the smaller color
beams inside the entire light beam. The green leaves
absorb all of the color beams except green. Only the
green beam is reflected back, so our eyes see the
leaves as green. The apple absorbs all of the color
beams except red. Only the red beam is reflected back,
so our eyes see the apple as red.
