Picture of Autumn Colours

As the summer sun fades away, the bright green of the trees leaves also fades, and the leaves take on the autumn colors or reds, oranges and browns. The green color is derived from the chlorophyll molecule.

The rich autumn colors come from the carotene molecules in leaves.
