Hi, in general, please ask this kind of custom coding question in the support forums.

However, in this case, I can see that the code that changes the color of admin's posts in Message Wall / forum threads and article / blog comments is in and I know that it came from this forum thread and was written by Pecoes.
 * w:c:galaxylife:MediaWiki:Common.js and
 * w:c:galaxylife:MediaWiki:Wikia.css

All it looks like you need to do is copy the two sections of code in that forum thread to your wiki, and then you would need to change the usernames of the admins in the JavaScript section of the code.

-- If you need help with this one, I'd recommend leaving a message for Pecoes as he's the one who wrote the code and so he knows it probably better than anyone else.
