You could go dark on the walls. Love the high windows, the table and chairs and the chandelier. A large vertical painting on the back wall would look good.

Thank you houssaon! What dark color would you choose?

Hi! What a lovely area! I think I would start with a rug. this will help you decide what colors you like in the area. Here are a few options for you:

Which came first, the chicken or the egg. In this case go out into the marketplace, either in person or online......houzz dining rooms is a good place to start......and check out your choices. Rug or color are both good starting places but looking at both at the same time will give more satisfaction in the end.
