The Davey Tree Expert Company explains, “As chlorophyll production wanes and leaves begin to shut down, turn color, and drop from the tree in the fall, other pigments become visible. The yellows, oranges, and browns were always there, only hidden. The red, pink and purple pigments, however, must be manufactured in leaves during the fall. These colors are the most variable from year to year, because their formation is the most dependent on favorable environmental conditions.”
