Admin Forum:Changing admin username color?

I have seen in many wikis that admins' usernames have a special color. I found a thread about it, in this wiki, but it's inactive and it doesn't say, where to do it. So, will someone tell me, how to do it and where to do it? 12:33, August 7, 2012 (UTC)
 * In your wiki's MediaWiki:Common.css put a[href="/wiki/User:USERNAME"] { color:COLOUR NAME !important; font-weight: bold !important; }

 * MediaWiki:Common.css does not affect the oasis skin. Therefore, I would also recommend adding a code like this to your wiki's MediaWiki:Wikia.css file:

Message wall username color
Since we have message walls now which don't use the "wiki/User:USERNAME" but "/wiki/Message_Wall:USERNAME" I have a question.

I use more than one username color change with such a code: a[href|="/wiki/User:USERNAME1"], a[href|="/wiki/User:USERNAME2"] { color: COLOR_CODE/NAME !important; } Why such a code won't work and what to do to make it work and display usernames in color message walls as well: a[href|="/wiki/User:USERNAME1"], a[href|="/wiki/Message_Wall:USERNAME1"], a[href|="/wiki/User:USERNAME2"], a[href|="/wiki/Message_Wall:USERNAME2"], { color: COLOR_CODE/NAME !important; }
