Autumn leaf color Japanese maple autumn leaves Autumn leaf color is a phenomenon that affects the normally green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, various shades of yellow, orange, red, purple, and brown. [1]. From vivid reds to golden yellows, the science behind autumn's colors reveals how weather, tree species and chemistry combine to create the seasonal spectacle.

Leaf color changes are among the most visually striking phenomena in the natural world. From the vibrant reds, oranges, and yellows of autumn foliage to the subtle shifts in green hues during various growth stages, these transformations tell a compelling story about plant biology, environmental conditions, and ecological interactions. Leaf abscission (the technical term for the dropping of leaves) begins with the degradation of chlorophyll.

As the green fades, yellow and orange pigments known as carotenoids are revealed in the leaves of many species. In other plants, pigments called anthocyanins accumulate in the leaves at this time, giving them shades of red and purple. Learn why leaves change color in the fall and see the chemistry of the pigment molecules responsible for different leaf colors.

The color change culminates in leaf abscission, the shedding of leaves from the tree. This protective mechanism allows deciduous trees to conserve water and energy during winter. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from the trees.

All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall. Under optimal conditions this process of chlorophyll loss is very orderly and allows the plants to resorb much of the nitrogen in the structure of the pigment.
