As the previous update had no effect, I suggest copying the code from here and then remove the undesired materials, as that code is functional.
Okay I'll give it a shot. Not sure if did it right or not but check it out.
Replace all of MediaWiki:Common.css with this, and replace all of MediaWiki:Wikia.css with this.

There we go, I did it :P
It works, thank you! :DHopefully there won't be any problems though...
You;re welcome, if there's any other things like this just ask :)

The line is at the very bottom of the page.
For all class colors in MediaWiki:Common.css.
There, I think I got them all :s
