Description
Colorful foliage during a mid-September Colorado autumn dazzles the eye. But why?
When leaves appear green, it is because they contain an abundance of chlorophyll. There is so much chlorophyll in an active leaf that the green masks other pigment colors. Light regulates chlorophyll production, so as autumn days grow shorter, less chlorophyll is produced. The decomposition rate of chlorophyll remains constant, so the green color starts to fade from leaves.
At the same time, surging sugar concentrations cause increased production of anthocyanin pigments. Leaves containing primarily anthocyanins appear red. Carotenoids are another class of pigments found in some leaves. The carotenoid production is not dependent on light, so levels aren't diminished by shortened days. Carotenoids can be orange, yellow, or red, but most of these pigments found in leaves are yellow. Leaves with good amounts of both anthocyanins and carotenoids will appear orange.
Leaves with carotenoids but little or no anthocyanin will appear yellow. In the absence of these pigments, other plant chemicals also can affect leaf color including tannins, which are responsible for the brownish color of some oak leaves.
Temperature affects the rate of chemical reactions, including those in leaves, and plays an important part in leaf color. However, it's mainly light levels that are responsible for fall foliage colors. Sunny autumn days are needed for the brightest color displays, since anthocyanins require light. Overcast days will lead to more yellows and browns

Thank you very much Barbara! There is a long, very personal story behind this photograph. For one thing, I had to forgo using 4x5 inch film and then having it digitized due to the expenses involved. And, the actual location of the POV is very meaningful to me as well. I appreciate your comments.
