Why do only some trees have leaves that change color?
Leaves change color because the trunk of the tree stops sending nutrients and water and other chemicals to the leaves.

Why do tree's leaves change color in fall?
Certain types of trees, known as deciduous trees, have leaves which will not survive the cold of winter, and therefore, the tree withdraws useful minerals from the leaves in the fall, so that those minerals will not be lost when the leaves die and fall off the tree. It is a process of nutritional conservation. The change in the chemical composition of the leaves causes a corresponding change in color.
