Copper ceiling. what color paint on walls?

would best accent with the copper? there are also beams going across the ceiling. beams and walls are currently painted a very putrid pinkish-beige. baseboards,trim, and moldings are painted off-white. the room needs rejuvination, and now that ive cleaned the copper to its original glory, i want the walls to coordinate . some suggestions for colors ive received so far are: cinnamon, brick red, saffron, sage green, burnt sienna, mustard yellow. what do you think? has anyone decorated with copper ceilings?
