Opinions on kitchen backsplash

[Curlysue]

We just moved into a new house in July. We have white cabinets, black granite counters, and light yellow walls. I want to put up a backsplash in the kitchen, and I want to do something to add some color. I like blue and green. Any suggestion on a backsplash that would look good? Appreciate the feedback. I don't have much vision for this stuff.

Maybe mosaic tile, bringing in some blue, green and yellow? I'd keep in mind what you can live with for a long time, though - you can easily repaint the walls, but IMO a backsplash is more annoying to change.
