The Flipping Arena

I'm sure this has been asked to death and the answer to it is probably around somwhere, but I've looked in all the stickied threads here and I can't find the answer.

It's pretty simple, though, what do the colours mean on people's names? There seems to be a whole spectrum, fading from dark blue all the way up to dark red. On most boards they maybe have three colours, one for members, one for mods and one for admins but here we have Blue, light blue, cyan, green, orange and red, just to name a few off the top of my head, what do they mean?

Thanks.

This:

so, what are black and yellow?

Jason has been playing with names a bunch lately. Yellow is usually the shortbus, something like being banned I think.

Do I rally have to apply for the regular's color?
