Hello. Sounds like you may want to ask your question in the forums. Or do a search -- changing username colors is a common request. It requires you to add some custom CSS code to Mediawiki:Wikia.css or Common.css, and it is probably easiest to copy code from a wiki which already has it and then customize the colors/names. :)

In terms of the background and icon, the best way to alter those is through Theme Designer.
