Personally, I'd keep the whole thing white. I'm a fan of the IKEA white gloss cabinet doors, which we have in our bathroom. The laundry's a utility area, and with white you can easily see any dirt that you track in from outside.

If you want to avoid this, check with the tile shop and make sure that any tiles you choose come from the same batch, although this may be a bit difficult if the floor/walls are different sizes/gloss levels.
