Colored Level Badges

I’ve notice many different drivers sporting many different colors signifying their level ‘badges’, yet when I look at mine, its white.

Does anyone know what determines these colors?

Thanks!

Thanx to the (what i assume) Infinite Prestige Levels we have now…, are the Colors of any significance anymore? i for one, don’t feel any special about getting a gold wristband anymore, or that treasured Platinum Star (which i worked hard to obtain in FH3, without any real recognition from T10/PG for the effort)
For Example: a Special Forza Edition Senna (to us) would’ve been a nice gesture…, We cannot feel bad for the ones that didn’t attain it, so i don’t see why u should feel bad for awarding something like that
