I personally prefer when the door color matches the trim. That's a lot of white, but with your aesthetic I think it will work. What shade of grey were you thinking?

I think a Black or very dark grey (Charcoal) would look amazing. It would help anchor the dark ceiling and tie everything together. White would be a safe bet, but I always like to do things bold.

Thanks for the comments! I am open to any shade of grey, but through the rest of the house we've used a lighter grey to balance the black and white.

I like bold too, but what I love about the black ceiling now is that it fools your eye and disappears making the hallway feel a lot larger than it is. I don't want to loose that so originally we were thinking painting them black but I'm second guessing it now

As long as you don't go with a grey that's super light, I think it will be fine. You don't want it to look like the doors just don't match the walls. Maybe you could just prime the doors and think about it more after they're primed? It will give you a better idea of how they would look white.

Thanks Aviva, that's a wonderful idea I didn't really think about!
