The Science: The leaves like our own skin have pigments. Chlorophyll is the pigment that gives the leaves their green color. Chlorophyll is what changes sunlight into sugar, it how the plants feed themselves.

The amount of sunlight decrease as we head into the second half of the fall. With less daylight, the plants prepare for winter and stop making chlorophyll. Instead, the trees and plants break down the chlorophyll. As the chlorophyll breaks down, other pigments begin to show their colors. The other pigments in the leaves are carotenoids and anthocyanins.

Carotenoids produce the colors yellow and orange. While, anthocyanins produce red, pink, and purple colors. It’s these pigments that give the leaves their beautiful colors.
