It is basically our extra room. It is big (don't know the measurments, sorry). It fits two desks, a couch & stool, coffee table, an excercise bike, and a TV, and there is still more room. The couch, bench, table, and desks need to be replaced. The exercise bike is black, and we'll hang on to that. There are a couple of file cabinet that are greyish olive (replace?). The carpet is beige-ish sunburn, and the windows will probably greatly soon have white shutters (other suggestions are welcome). What color(s) do you suggest would look good within this room?

Thank you :)
