Are There Yellow Crepe Myrtles?

According to yardner.com...

"Foliage: Crape myrtle leaves appear somewhat late in the spring, particularly on those plants that are new and young. They grow opposite each other, or sometimes in circles of 3, along shrub stems. Broadly oval, they grow to 2 to 4 inches long and 1 to 2 inches wide. They have smooth edges and rounded bases and tips. When they appear in the spring, they are a yellowish or bronze color that changes to lustrous medium green, slightly paler beneath, as they mature.

In the fall they turn reddish, red-orange or yellow, depending on the variety, before they drop. White-flowered types have yellow fall foliage; pink and reddish ones have yellow, orange and red leaves in autumn."

Hope this answers your question.
