If you mean leaf color, the two major 'types' of tree are deciduous - such as oak and maple trees - and evergreen - which are mostly conifers, such as pine trees.

Deciduous trees lose their leaves in the fall, and before doing so remove all useful nutrients and dump all waste into the leaves, making the color change from the summer green to some variety of orange to brown (depending on the chemical makeup of the leaf, the types of waste dumped into the leaf, and the hydration of the leaf).

Evergreens, by contrast, do not use their leaves in the winter, and so never go through this process, and thus do not undergo leaf color changes.

If you are interested in color changes in the bark or wood itself, then the answer is vastly more complex and you should research individual trees, as there are too many small and large changes to mention here.
