Hi - This looks like some early fall coloration due to stress conditions such as hot weather. Several types of trees are showing stress symptoms at this time of year, but it is nothing to be too concerned about. By this time in the season, trees have stored enough carbohydrates (food reserves) to be able to put out healthy new growth next season. Just give the tree normal good care. Water during periods of drought and avoid excessive mulching. Mulch should be no more than 2-3" deep and keep it a few inches away from the trunk.
