I'm moving into an apartment that has dark hard wood floors. I have a light grey couch. I was wondering what color should I paint the accent wall? What color should I pick the accessories to give light to the room? Should I add a rug, if so, should it be a shade of the accent wall? And lastly, which wall should be my accent? Should it be the first wall you see when walking in? Or the wall the back of the couch will lay against? Thanks guys!!

Originally I was thinking grey/white with touches of yellow or green.
