Seeing Green

August 31, 2018

Why does a leaf look green? Great question! It has to do with light and how humans see color. Light bounces off objects and into our eyes. In this case, the leaf is the object. The sun shines white light onto the leaf. (This light contains all colors of the rainbow.) The leaf soaks up most of the light. But it reflects the green light. This light bounces into the eye.
