Leaf color

Driving around town one sees gorgeous reds and oranges and yellows. It's like being in a paint box! So what causes the leaves to change colors?

Look in Access Science @ McGraw Hill in GALILEO. I used the search term "Autumn leaf color" (in quotes). Photoperiodism seems to best explain the change in colors.
