vBulletin 4 Request - Change background color of forum header based on forum ID

[Raptor]

I've seen this mod for 4.1.x but does not work on 4.2.x

I have forums with plain color background in forumhome - basically want a couple of them to have a different color background

Like so:

--------------- Added [DATE]1508911464[/DATE] at [TIME]1508911464[/TIME] ---------------

This is the section of relevant code in the html

<div class="forumhead foruminfo L1 collapse">
		<h2>
			<span class="forumtitle"><a href="forumdisplay.php/324-Gamers">Gamers</a></span>
			<span class="forumthreadpost">Topics / Posts&nbsp;</span>
			<span class="forumlastpost">Last Post</span>
		
			<a class="collapse" id="collapse_c_cat324" href="index.php#top"><img src="images/collapse_80b.png" alt=""></a>
		
		</h2>

		
	</div>
