Not sure what you looking for Just get Benjamin Moore's light and neutral color chart bring into your home where you can see what works best under the "true" light condition in the room. Picking colors from a picture could be deceiving. I see this all the time, people bring pictures to the store or some other material or a cabinet door, etc they pick a color which looks good under the store light condition and when they paint everything in the house it looks way off.

Best way to select paint is get a few samples of paint that you can get for a a few dollars, and try them out on your wall and see what works best.

Are you going to paint the wood too?

If it were me, I would pull the colors out of your stone work, which is the star of the show. Pick the lightest color---perhaps the grout color--and paint the ceiling with it.Then pick another color a little darker out of it and paint the walls, including the wood. It will all flow together beautifully.
