Pretty granite! I think #2 and#5 are too cool toned for it. I lean toward the green or a dark blue, but make sure that the shade goes well with the stone.

Hello, here's an article that may give you some ideas on how to choose the right shade of white for your wall: https://www.remodelista.com/posts/remodeling-101-how-to-choose-the-perfect-white-paint/

I think the revere grey is the way to go. The other is too white and makes the contrast of the navy and blue cold and stark. They grey acts as a better connector of the two colors and is in the same color palette of the existing colors in the kitchen. Definitely, keep the walls neutral and don’t introduce another strong color there. If you want a pop or another bright color do it with accessories such as a bowl, kettle or plant pot.

Consider BM Soleil, AF 330, is a light buttercream color, somewhere between yellow and cream. It's beautiful, and the Aura paints have excellent coverage over darker colors.
