The more favorable warm, sunny day/cool night temperature cycles that occur in early autumn, the more likely that fall season is to experience vibrant colors with lots of reds. Leaves that get the most sunlight will develop red leaves, as the sugars inside them are `baked` into the red anthocyanin pigments. This is the same process that causes many apples to only be red on the side facing the sun as they grow. Trees that don`t receive as much sunlight will reveal the orange, yellow and brown colors, caused by the carotenoid and xanthophyll pigments that are already present in the leaves, but are hidden under the green until the chlorophyll breaks down.
