Decreasing amounts of sunlight
In the fall, leaves stop producing chlorophyll, the pigment that gives them their green color. As the chlorophyll breaks down, other pigments such as carotenoids (yellow and orange) and anthocyanins (red and purple) become more prominent, resulting in the vibrant colors we see in autumn leaves.
Some trees change color before others because they are more sensitive to changes in temperature and daylight. This sensitivity triggers a process that causes the leaves to stop producing chlorophyll, revealing the other pigments in the leaves that create the vibrant fall colors.
