Painting an accent wall is an easy way to add drama and characterization to a room. The trick is deciding what you want the accent wall to do for your space. In a home with an open floor plan, choosing the right wall is key. Ideally, you should choose the wall that has the most interesting feature that you want to highlight. For example, if your living and dining room combo has a fireplace, the wall around it is the ideal spot to paint. However, if you plan to use your accent wall to visually divide the room into living and dining zones, you can paint the wall behind your dining table or sofa as the room’s accent.
