The chlorophyll (the green stuff that does photosynthesis) inside the leaves die out in the fall/winter because they don't make any food in the winter, just the food they saved up. Then, there are other colors (the yellow and orange) that show since the chlorophyll dies out. Sometimes, the sap gets stuck in the leaves and make it look purple-ish or red-ish.
