Autumn Leaves Changing Color
Frederic Edwin Church, "Autumn Woods," ca. 1870, Cooper Hewitt, Smithsonian Design Museum, gift of Louis P. Church Autumnal leaves in vibrant hues are a beautiful part of the season, but those leaves are also a vital part of keeping trees alive.
Trees that have leaves that change color in fall. Learn how leaf pigments, length of night, and weather affect the autumn color display of trees and shrubs. Find out which species produce which colors and how they survive winter.
Why Leaves Change Color in the Fall - Chemistry
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] The phenomenon is commonly called autumn colours[2] or autumn foliage[3] in British English and fall colors, [4] fall foliage, or. 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.
Explore why leaves change color in fall, the role of sunlight and pigments, and top tips for spotting the brightest autumn foliage this season. In many places around the world, autumn is marked by the slow, beautiful change of green foliage to vibrant reds, oranges, yellows, and purples. Learn why leaves change color in the fall and see the chemistry of the pigment molecules responsible for different leaf colors.
Why Do Leaves Change Color? Here's The Scientific Explanaition
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.

One way trees save energy for winter is by dropping their leaves.
Why leaves change color and fall down in autumn, according to experts
As autumn progresses, a tree will send a substance to each leaf called an enzyme. Have you ever wondered why leaves change from green to an amazing array of yellow, orange and red hues during the fall? Leaves get their brilliant colors from pigments made up of various color-creating molecules. During the warm, sunny months, plants use their leaves to turn sunlight into food energy, a process called photosynthesis.
