What Causes Fall Colors?
The chemicals - Four main groups of biochemicals are responsible for the various yellows, oranges, reds and browns that we see in the fall: Chlorophyll, Carotenoids, Anthocyanins, Tannins. Each has its own color and chemistry. As the amount of these chemicals vary, they will cause subtle variations in color from one leaf to the next, or even from tree to tree.
