I see now, thanks. Maybe an option next to the color like "More Colors"? That's what I would like to see.
Following up on MattKan's post about the setcoat, setnick, setskin, etc. commands, I think the platform may be a factor. As opposed to the computer, iDevices are owned by people of all different ages, and the app is not restricted to a certain age group. Seeing as some very young players may be confused by this type of command, the interface may purposely look more friendly to anybody who picks up the game. This includes menus, guilds, profiles, etc.
On a side note, if you try setnick on the iPhone and Facebook servers, the text doesn't appear, just as it behaves when you unstick, showlag, setsword, or setshield. However, setnick does not work. Obviously, something is scripted in there, just not completed!
