Well the colours (uk spelling) are as follows

Dark blue italic - Site administrators who can fix most things for you
Green Italic - Site moderators who ensure smooth running of the site
Light blue - normal members

and our very special colours who make this site possible with out bankrupting me.....

Red - our advertisers, please support them!
Dark purple - supporting members who have donated to the site.

Cheers

Stuart

PS just to complicate this some of our advertisers are also moderators - so double thanks for both time and money to make this RB community what it is.
