Colored Username

Does anyone know of a hack (or can point me towards something similar that I could maybe altered slightly) that gives members the ability to choose an from a dropdown menu in 'usercp > options' that controls the color of their username (predefined by admin)?

EG:
Car Owner (#FF0000)
Van Owner (#0000FF)
Truck Owner (#008000)
Motorbike Owner (#FFFF00)

I've seen one for usergroups but want it completely independent groups.


S.C>

Use the hack for usergroups and then create public, secondary usergroups for those terms.
