If everything is already cherry and brown I would get something contrasty and there's only one on your list - blue.

Open floor plan. Kitchen has cherry color cabinets, flooring is cherry (we may change to some kind of brown). Opposite end of these cabinets is family room's fireplace. I want to do an accent wall color. Should I do it on the fire place wall or the adjoining wall against which the couch will be? What color couch would blend the kitchen and family room together - thinking of getting Sherwin Williams Grey Heron color for the walls (except the accent wall). I was leaning towards some kind of coral/orange (Persimmon/Sunset/Ravishing Coral/Coral Sand) or taupe/rose(Cabbage Rose/Oleander) or Dignity Blue, from Sherwin Williams, for the accent wall.

Changing cabinets is not happening. Just the paint color, furniture and possibly flooring for now. Help me choose. Thanks!
