What three factors give leaves their many fall colers?

The vibrant colors of fall leaves are primarily influenced by three factors: the presence of pigments, changes in temperature, and daylight duration. Chlorophyll, which gives leaves their green color, breaks down as temperatures drop, revealing other pigments like carotenoids (yellow and orange) and anthocyanins (red and purple). Additionally, shorter days lead to a decrease in photosynthesis, prompting trees to prepare for winter, further enhancing the display of autumn colors. Weather conditions, such as sunlight and moisture, also play a role in the intensity of these hues.
