PLANTS WITH FALL COLOR Plants change color because of shorter hours of sunlight and cooler temperatures. These two conditions trigger the chlorophyll in the plant to break down. The pigment that kept the leaves green throughout the summer now causes the leaves to turn red, orange, or yellow. The intensity of the color is controlled by the weather. A combination of sunny, warm days and cool nights gives the best color. Of course, the healthier the tree, the better the color.
