Roberto; I think you can do better than white. Are those dark cabinets that have been re-finished in white? This blog post may help: Backsplash Backstory

Wall color will remain yellow? Can you post a picture with a cabinet door installed?

I would look at a few different options at a local tile store: Think about a gray to work with the counter top, maybe a glass mosaic. Another option would be a mosaic that has some of that yellow in it with a gray. Finally I would look at some options that are in the muted yellow family like the wall color. I would love to see what a door looks like.
