I like the pumpkin color. You can change your accessories very easily with it. Red, blue, green and even a plum color would work well. I'm considering a similar color for my foyer, I think it is called Camel. Good Luck :)
You can also hang a swag curtain above the area to define the space. If there is an archway simply place a decorative rod covering the area and hang a curtain on it. Let us know if you solve the problem :)
