That's not 100% accurate anymore, but it's the general groups. Our administrators are currently a special gold-outlined red that I'm quite jealous of, and our active member color is the username color you've got! :) Finally, Jared, our server technician, is orange.
There are also a couple special username colors that come out as rewards for official Iwaku events. I believe none of those are currently in use, but if you ever click on a name that's an unfamiliar color, you can go to their profile page. It should list the reason for it as a banner under their name, if it's not one of the defaults in the spoiler above.
