In summer, most leaves are green. They are full of a green material called chlorophyll. Chlorophyll helps the tree make food from sunlight.

In fall, the days get shorter and colder. Trees stop making as much chlorophyll. As the green fades, other colors that were hiding in the leaf start to show: yellow and orange.

Some trees, like maples, also make new red and purple colors in the fall.

Soon the leaves drop to the ground, and the tree rests for the winter.
