Paint it black
In 2008 I got my first pair of wheels with Profile hubs. I don’t know why I ordered them in white, clearly violating my no-more-than-2-colors-on-a-bike rule. The error got later fixed by building a 100% black and white steed. Recently I decided to paint the hubs in black, and I will now forever only buy black bike parts. The frame can be any color, but everything else must be black. This way, parts can be re-used and swapped between bikes.
Damien told me that the paint would crackle, but so far (3 years in) everything is fine.
