Fall colors refer to the vibrant hues that trees and plants display during the autumn season. As temperatures drop and daylight decreases, chlorophyll—the green pigment in leaves—breaks down. This process reveals other pigments, such as carotenoids, which produce yellow and orange shades, and anthocyanins, which create red and purple tones. The intensity of fall colors can vary based on several factors, including tree species, weather conditions, and soil quality. Regions with cooler nights and sunny days often experience more vivid displays. Popular locations for viewing fall colors include national parks and scenic drives, attracting many visitors each year.
