Wanted to shift the focus of wall between 2 openings into the livingroom/dining room feom the hallway. Dwcided to make it a fireplace wall. Walls will be painted dark grey, with white trim and crown moulding. Lower section of the wall has electric fireplace, with white marble mosaic. will have wood ledge/mantel. Not what sure what to do on the upper part. (Texture? Colours?)) Might place a pixture frame. Any suggestions?
