| Why do leaves change color in the fall months? This is because with shorter days in the fall, the tree's chlorophyll breaks down, leaving other chemicals that cause color changes. The chlorophyll produces a green color, xanthophyll produces yellow, carotene produces orange, and anthocyanin produces red. Brighter colors are more likely when late summer is dry and autumn has sunny days and cool nights. |
