Every autumn, the world transforms into a blaze of reds, oranges, and golds—but what’s actually happening inside those leaves?In this episode, Gordy unpacks the science of fall colors—from chlorophyll breakdown and nutrient recycling to why some trees create new pigments right before they drop their leaves. You’ll learn what triggers the brilliant reds of maples, the golden hues of birch and aspen, and why the spectacle of autumn foliage is as much a chemical strategy as it is a visual feast.Discover how anthocyanins act like sunscreen, how carotenoids make corn and carrots glow, and how the balance between sunlight, temperature, and trapped sugars can make or break a good fall season.It’s not just pretty—it’s evolutionary economics in color.Sources • National Park Service.
