I second the wrap idea, easy to to, easy to remove at a later date. That said, I've owned white bikes, I didn't mind the color and they're more visible.
That reminds me, white helmets are pretty visible compared to most colors, and if it's hot and sunny where you ride, they ride cooler as well.
And in many jurisdictions, white tanks and helmets look like cops. Car drivers are more likely to notice cops and not cut them off.
