I feel like your kitchen would make more sense with warmer colors than gray or blue. You could do a really warm gray. I would go Benjamin Moore and grab all the grays that you can find and lay them on your counter and see which one looks the most cohesive with it. Avoid purplish gray or anything with too much green. Try to find one with a brown undertone. I just did my great room in Stonington Gray, but I think it's slight green undertone wouldn't play well with your cabinets.

I think gray will look better and more attractive. Go for it or If you are looking for cool colors then olive green will look best.
