Yes, gray works quite a lot better with a projector than white. But it does also depend a bit on your use case, you would choose a different paint for a very dark room than one with a fair amount of light pollution. Some people get quite involved with paint formulation, and for a while I played that game, but if I ever need to build a bigger screen I'm just going to buy one. Halfway decent ones aren't very expensive now.
