what colours would match a dark brown leather sofa apart from orange?
I think it is important to have bright or even wooden windows. This will make the atmosphere more cosy. Pay attention to your exterior door. You can get great ideas from home decoration games - http://www.dressup247.com/category/30/Room-Decor/1.html. Sometimes they might be very inspirational. I would agree with the AKA fighter for the light shades - cream, eggshell, taupe. At least at home is like this. But you know - make it as you feel it will be comfortable for you because you will be living there. ;)
