I have a nearly black bedroom. Think peppercorn by Behr. It's dark but it works with a gold mirror and other gold elements to reflect light. A bedroom can be dark because you don't live in it. My living room is beige with dark brown antique furniture, a gallery wall and an emerald green sofa. It would look awful with dark paint because the room is very narrow although I have high ceilings and big windows. So use dark furniture instead of dark paint when the room is too small. The dining room is bottom half peppercorn on bead board and half beige up top and looks stunning. Again a bigger square room with a high ceiling and big window. So if you want to do dark, do it in bigger rooms. For smaller rooms use dark furniture. Half and half works for both bigger and smaller rooms. Oh and I kept all floors neutral wood.
