All or Nothing
By incorporating one dark or patterned wall into a room I think it makes the space feel disjointed and unbalanced. In my opinion, a successful room should have many things that the eye dances upon and no one feature should jump out at you. Many people use these ‘accent’ or ‘feature’ walls as a way to create a focal-point within a room. I think it is much chicer to do this with art and furnishings. Thinking of a navy accent wall? Why not paint the entire room navy and incorporate a massive white canvas over the sofa to act as the feature. The room will actually feel larger as the corners and edges of the walls will blend in and become blurred. The eye will naturally look at the ‘stuff’ within the room and not at the room itself.
