In many parts of the world, autumn is a time for leaves to turn dramatic bright colors. Most of those spectacular colors of autumn have actually been in the leaves all summer, however they were “covered up” by the dominant green of the chlorophyll.

The brightest colors are seen when late summer is dry, and autumn has bright sunny days and cool nights.
