Bedroom Paint Color

 We were thinking of doing two colors in our bedroom; a slate blue and a bluish gray.  Styled like they do in class rooms.  We are thinking 3 down on left card with 2nd down on right card. 

Or a brown.  The brown idea came because we have some art that could go up in the bedroom and it would provide a great base for all the colors of the art.  shrug.  but our bedroom has two walls with nothing to break it up and that might be a lot of brown and could feel to dark.  Was thinking of either of the middle ones.
