Stretches of FR 300, 321 and 218C last weekend offered an extravagance of fall colors. The yellow colors in fall leaves come from leftover compounds called xanthophylis and carotenoids that shine through once the green chlorophyll fades away. By contrast, leaves convert carbohydrates into the brilliant red compounds for reasons that still mystify biologists, since the tree will shortly shed the leaves. The red compounds might reduce frost or insect damage.
