Answer: It is really difficult to identify a tree without seeing it, but the tree ma be a Honey Locust, or an Ash (Fraxinus pennsylvanica) Both have pinnately compound leaves and both show the red/green fall coloring. Either grows well in your gardening region. The Honey Locust has a broad, rounded canopy; the Ash is more broadly oval. Both reach 50' high by 30' wide at maturity.
Aside from these two suggestions, you might want to visit a local nursery at this time of year - the foliage will be changing colors now so you'll have an idea of what will provide fall color in your area.
Best wishes with your landscape!
