Hey need some help

Hey well im new to this and not sure were to find it, but i was wondering can someone give me a link or point me in the right direction for the mod which enables me to do this:

Have like the ranks at the bottom:

[Admin] [Super Moderator] [Moderator] [VIP] (i would choose the ranks)

and then they have the colour of the rank with there name:

E.g. Admin = red

there username would be red if there admin.

This way it shows there rank and also gives the colour scheme of the rank at the bottom, seen it done on sites before but i can't find the mod.

Help is appreciated, thanks.
