How do get coloured usergroups??

[Killy01]

Well I was just wondering if you could have coloured usergroups in vbulletin much like you can have coloured usernames. In the picture below I would like the text that says "Administrator" (Underneath my username but above the image) to be a different colour, how would I go about doing this? would it be available in the admincp or would it be a template edit?

Thanks
