. When the leaves begin to stop making. As the Sun becomes less intense in fall chlorophyll production slows down. When this happens it is harder for the chlorophyll in.
For example in Maple trees the bright red that shows up is a result of excess glucose being trapped in the leaves. One type of natural chemicals left are carotenoids which is what makes carrots orange. This is why leaves change color in the fall.
When chlorophyll is broken down in the leaf the green colour disappears. Inside a leaf there are many pigments but during the growing season these pigments are obscured by the green of the chlorophyll. The orange packages are called carotene.
Sugars that can get trapped in the leaves produce new pigments called anthocyanins that werent part of the leaf in the growing season. Have you ever wondered just what the actual reason for the leaves to change colors in the Fall. Carbon dioxide is obtained from the air.

Why do leaves turn color in autumn. Darker red leaves are the result of a chemical change. The green packages are called chlorophyll.
The yellow packages are called xanthophyll. Anthocyanin is another pigment and turns leaves red or purple. In the winter there is not a lot of sunlight so deciduous trees and plants that lose their leaves in the fall trees begin to stop making food.
The trees use a bright green pigment called chlorophyll to absorb the sunlight they need through their leaves. The colours we can see in autumn are from what is left behind in the leaf and this ranges from yellow to orange to red maroon and brown. And these other pigments now emerge turning leaves yellow or orange.
Autumn means leaves are turning different shades of red orange and yellow and falling to the ground. Photosynthesis converts sunlight carbon dioxide and water into glucose which the plant consumes to grow. Chlorophyll transforms sunlight into food through a process called photosynthesis.

Soon the tree does not have enough sun and water to make both its food and Chlorophyll so it stops making Chlorophyll and the leaves return to its natural color.
