Hi Julie,
I'm sorry; I'm not going to be much help with the paint color on the walls in this kitchen, since we did a custom color mix onsite. I've found that there are so many things that affect the paint color--the floor and cabinet materials, the lighting, the windows, and so on--that it only makes sense to adjust colors onsite to get the look you want. In this case, my advice would be to sample a few paint colors that appear to match the color in the photo, and then adjust the samples as needed to make them look good with the rest of your room (and the rest of your home).
Good luck, and have a good time experimenting.
