There are no less than a million grays. You must test in your own home , in your light. I would aslo paint out the dark trim to match the cabinetry "white" which is impossible to say which, from a photo

You want a warm gray, and one that errs on the green side, versus blue. A good paint store can help you, and no matter what......go half !!! the tone you see on the paint chip you want: )

^agree with Jan.

Would add one more thought. A gray of any kind in a low light situation, might not be the best choice. Are you open to lighter, brighter colors? More in the "off white" zone?

Gray will really brighten your home : (
