BM's ceiling paint is Chantilly Lace, if memory serves. If you're looking for something other than white, well...I've seen rooms with colour on ceiling but not paired with white walls.

Is there a reason you couldn't just do the ceiling in Chantilly Lace also? I've actually been to a few houses where the walls and ceiling were all Chantilly Lace (coincidentally enough) and it looks fine to me.
