I think I may have found the solution here. The problem is, I have two of these exactly same niches on the first floor. Do I do the same thing with them, or different things. They are not directly next to each other. I also have a much wider/bigger one behind a serving bar. I was thinking of painting that one like a dark brown, or some accent color, and then maybe hanging 3 square mirrors or pictures. But now that I think about that, the mirror frames would probably blend into the wall if I did it in brown. Ugh. Good thing I don't have money to decorate and am mostly just dreaming...
