The color commonly associated with the autumn season is orange. This warm and vibrant hue reflects the changing foliage as many trees and plants transition from their summer greens to shades of yellow, red, and orange. The striking colors of autumn leaves are due to the breakdown of chlorophyll, revealing pigments such as carotenoids that produce orange and yellow shades. Orange evokes feelings of warmth, harvest, and coziness, often linked with seasonal festivities like Halloween and Thanksgiving. In various cultures, the color orange symbolizes change, energy, and the natural beauty of the season's transformation.
