This year the colors of fall have been better from what I’ve seen in the past. For whatever reason. Is it because it got cold early, was there more precip.? For whatever reason the visuals have been stunning. I looked for some answers to this question and found this:

The two primary pigments are carotenoids that produce orange, yellow, and brown colors, and anthocyanins that are responsible for resplendent reds. The orange pigments (carotenoids) are present in leaves year round and get to shine when the green chlorophyll takes a break. Because the orange pigments are constant, their showiness in the fall is predictable. But, the red pigments (anthocyanins) are created in the autumn in response to light, plant chemical changes, temperature, and water supply. This is where weather affects the brilliance of the fall color display.
