That tile is what our backsplash will be

Blue can be super hard to get a good match with. If using the blue tile, I'd do the walls in something other than blue. Also try taking a tile to the paint store and see if they can mix up a sample that is a closer match.

The tile is more green than blue. What about the revere pewter? Can you see all three pics?

I guess I'm asking if I should try to match the tile or get something contrasting so it will stand out more?

I wouldn't use blue unless you are trying to kill your appetite. It is a good color for spaces you want to be calm and sedate like the bedroom or bath. orange could be a wonderful compliment to the aqua blue glass tiles and nice for kitchens. If you get a lot of sun go towards cool- if its a bit shadey go towards warmer shades..

I was looking at Benjamin Moore's site [it's about the easiest paint website to use] for your tile color, and think you would be wise to paint the kitchen either a color a couple of shades darker than the tile or a couple of shades lighter as that color is very hard to match. Here are a few ideas based on the color I see on my monitor:

I think the Palladian Blue clashes. Keep it classic and neutral.

If I would have such gorgous tile, and white cabinets I would use some wery light grey or blue/green (sea colours). From Benjamin Moore site for example Ice Blue, or Sweet Bluette may be Sweet Dreams or even something lighter.
I would like to recommend site with palette of colours which helps with proper matching. http://design-seeds.com/
