I helped found a new "Supergroup" (guild) and part of the neatness of it is that you can choose two colors for your SG. You can then (as a member of the SG) use those two colors to make a Supergroup-color-scheme for your character. Here's mine, and I really like it -- more than my original colors, even.
Here's the other co-founders and I, showing off.
Here is a teammate of mine (a Controller, like an Enchanter+cleric mix) resurrecting another teammate. My res spell looks so much cooler.
