We found this one multicolored maple leaf. It really represents how trees get their colors. The green is the chlorophyll that you see in the leaves during summer. As daylight hours shorten during the fall the chlorophyll disappears allowing the yellow and golds that were there all summer to show. The red is produced by the sun's reaction to the sugars in the leaves. This year we had lots of sunlight and rain making for vibrant red colors. This leaf was shaded on the back half so that the sunlight and sugars couldn't do their thing.
