I agree that white ceilings are becoming boring, especially since the explosion in color technology and acceptance/newfound bravery by the public in general. And, I think from a decorating stand point, they're not the go to they used to be. However, they still provide the greatest luminence. I try to encourage percentage formulas of the wall color, other complementary colors, even using flat versions of the wall color when a sheen is used on the walls, which is a nice effect.I don't like rooms painted with white ceilings as a matter of tradition or whatever. BORING and really a throw back to gas light days when the only safe place to put a light fixture was in the middle of the room. You sought as much reflection from white as possible I guess.
Anyhow, I too like using contractor grades of whatever sheen (fewer options in contractor grades) for ceilings. Super Spec from Ben Moore or SW's Pro Mar can save quite a bit per gallon and you do not need washability and so forth in a ceiling paint.
