Questions about mods should be asked in the mod thread, and you shouldn't post the entire code for a mod. Also you should also use code tags.

That said, the problem is that the mod changes $lastpostinfo['lastposter'] which is not just used to display the name. You would probably need to change the code to something like:

$lastpostinfo['lastpostercolor'] = $select['opentag'].$lastpostinfo['lastposter'].$select['closetag'];

then find the place in the template where lastposter is used to display the name, and change it to lastpostercolor.
