Why Does Fall Foliage Turn So Red and Fiery?

There are different thoeries about the color of beautiful autumn leaves.  The variation in color occur for many reasons and  in different stages of a tree’s life cycle.  Our eyesight remind us that nature a living being as seasons change.

Leaves scream their final cries in color before dropping to the ground. Their shouts — in golden, crimson or scarlet — eventually fade to brown bellows, and their lifeless bodies dry up on the forest floor. It absorbs their crinkly corpses and that’s it — worm food. The fall of a leaf in autumn is an orchestrated death. A complex, brilliant, beautiful death.
