It will look amazing. I have oiled oak floors (and solid oak dining table). My kitchen units are painted f&b Charleston Grey. And walls are Fired Earths Basswood (more towards cafe au lait than grey). Worktops are bianco carrara marble. I have grey concrete foscarini pendants over my island and Tom Dixon Beat Stout pendants over dining table in black and reclaimed cast iron radiators in anthracite.
I guess mine is more of an oak grey, griege and brown sort of thing but its still amazing.
