It depends the look are you going for and the color of brown. Charcoal with white and hints of orange are beautiful.

Could you be more specific? For example, are you trying to match furniture, accessories, paint Color,or all the above?

I love Earthly colors in the living room. You can attach you living room and couch pictures but if you want, here are some of the brown living room ideas I find cool.

Will you post a picture so we can see the color intensity. It will help. Thank you.

Anything goes with Dark Brown. I really can't think of a colour that wouldn't. You have not put anything into ideabooks so I'm not sure what you would really want. But here is one example from a client of mine that did a custom dark brown sofa. She loves it!
