You could use theme-source

In MediaWiki Using the same elements as .portable-infobox add the theme for "Series2" .portable-infobox.pi-theme-Series2.pi-background { background-color: xxxxxx; }

In Template:Episode Add theme-source 

Using Template:Episode Include an additional variable. As no theme has been setup in MediaWiki for the original series, this will be ignored {{Episode
 * series= Series2


 * name=Chapter One: The River's Edge
