During the long process of being rebuilt by Autobot Ratchet, there was a lot of time to think. Autobot Jazz digs his Earth vehicle form, but the silver paint job got scratched too easily, and dust stuck to it like cyberflies on old oil. Also, it wasn't nearly eye-catching enough. Just because he's supposed to be in disguise doesn't mean that he can't be noticed. With help from Bumblebee and Autobot Ratchet, he picked this color scheme as the one most likely to get him appreciative looks from all the humans the passes on the freeway.
