why do the leaves turn colors in the fall

The vivid yellow and orange colors of fall leaves have actually been there throughout the spring and summer, but we havenБt been able to see them.

Burgundy and red colors are a different story. Dana A. Dudle is a DePauw professor of biology who researches red
