What colour would good with this?

I've seen that color on the show "Sell this House" (Tanya Memme). I would use a beige. If you're really adventuresome, a red would be bold, vibrant, modern, and uniquely sharp. Try looking into some wallpapers-get a unique design with an array of colors instead on settling on just one. I think painting the walls opposite the brown would be a bit boring. Or you could go with a beige and maybe a wall border at the top or middle of the wall.
