I think it would be easier to recommend what would look best if we knew a few more details and maybe had pictures of the space? Is this for the whole house or one room?

entire house....i just thought after furniture decor etc, cant go wrong with white....i'll take some photos tonight...its a new build out...

I don’t think you can go wrong with a simply color scheme like white and grey. I think it leaves a lot of room for many styles of decor.

white would be nice and neutral there. I'd go for a soft white -- like BM Swiss Coffee or Navajo White. pure white might be too stark and cold next to the concrete.

Can the ceiling be one shade or white Swiss coffee and the walls behr poplar white for the entire house? How is it typically done? I’m was thinking of having one color for walls and ceiling.
