I am considering installing a wall unit on either side of my fireplace. My existing wall color is a neutral beige and the fireplace mantle is white, with a t.v. hanging above the fireplace. I have looked at pictures of wall units and they are usually white. What do you think of painting the wall unit the same color as the wall so it will blend in. I want to keep the fireplace, t.v. and mantle the main focus point. Any advice would help.
