Many of the elements in your kitchen are "warm" - that is OK as many newer kitchens are moving back to a more warm feeling. A mistake frequently made is attempting to go "cool" to be modern - but modern does not have to be cool. In your pictures the Repose Gray is reading a bit cool - fine with the neutral cabinets but not working so great with the warm backsplash and counter. Keep in mind computers don't see true color, so maybe it is not a problem in reality - but trying to mix warm and cool has gotten many a person with a kitchen that is just not blending well. Many of the warmer new kitchens are using white, cream or warmer grays - which often read a little green.
Because of the movement of the grain with some oak cabinets, they tend to look best with a simple backsplash. A complex backsplash will be too busy. One good way to choose a backsplash is to take a light color from the countertop and use that in something simple - subway tile or other simple tile. You might find getting a tile that works with both the countertop and the wall color to be a little difficult - if so, changing the wall color is easier than the counters.
Consider starting with lighting since the lighting may change how you feel about the color of
other elements you are thinking about.
