Beautiful yellow color of Maple tree in the FingerLakes of NYS. The four primary pigments that produce color within a leaf are: chlorophyll green; xanthophylls yellow; carotenoids orange; and anthocyanins reds and purples. Aphids are attracted to yellow leaves more than red ones. Trees that expend the energy to color their leaves red may benefit from fewer aphids and fewer aphid eggs.
