I like the silver. Given the simplicity of the bike's color scheme, I'm not sure anything other than navy, silver or black would look particularly good--but I'm pretty conservative when it comes to color/pattern etc. Cinelli offers several patterned tapes that might appeal to you. I'm sure other brands do, too, but I'm partial to Cinelli so it's the one I'm most familiar with.

By the way, if your bike is going to need to be serviced soon for new cables or any other maintenance that requires the bars to be unwrapped, you should probably wait to have it all done at once.
