Are all pigments in maple trees Green?

No, not all pigments in maple trees are green. While chlorophyll is the primary pigment responsible for the green color during the growing season, maples also contain other pigments such as carotenoids, which produce yellow and orange hues, and anthocyanins, which can create red and purple colors. These pigments become more visible in the fall when chlorophyll breaks down, leading to the vibrant autumn foliage for which maple trees are well known.
