Gray Walls

As much as I love black walls, I think I love gray walls just a teensy bit more. A brooding alternative to white, gray walls add a sense of drama to a room.  Even small rooms seem bigger with gray.  In fact, I think I prefer gray in smaller rooms.  What are your thoughts?  Too drab and dreary or just the right amount of drama?
