Usually greens and warmer blues and some greiges can work with oak beautifully; in your case though, I see a backsplash that seems a bit pink-ish to me? Am I right? I know monitors show colors differently. How you'd describe the backsplash color, or can you do a close-up?

If I'm right-everything that goes green or gray or blue direction will contrast your backsplash. Great when one wants to contrast backsplash, but I believe that yours is stone and somehow will be a mistake to contrast it(no great explanation this moment..I'll think of it), but will be much easier to draw the color from it. Which leaves us with creams yes..maybe a tiny bit pinkish ones, like Everlasting by BM. For example. In any case, never pick a paint without trying it in your space in your light first.

whatever can be a perfect cream for room X will turn peach in room Y. whatever will be amazing greige in hundred other homes can turn steel gray in yours. So much depends on your light.

Now, all my advice can be thrown to hell if you decide to change the backsplash.

And I might decide to change the backsplash-I see no particular rationale behind the existing backsplash. It doesn't neccessarily works well with granite or with cabinets. I don't see why the previous owners installed it. Especially when one backsplash, the granite one, already exists.

If you decide to paint the cabinets at some point-you're limited, once again, because of the backsplash.

In short the backsplash demands lots of consideration and dancing around it, without being superbly great element. If to change anything-I'd plainly get rid of it, and be much freer in all my other choices.

But if you like it/decide to leave it for other reasons-it must be considered when you choose your paint.
