/*
Sets the colours of pages based on category.
Currently requires the following JS snippet: https://www.mediawiki.org/wiki/Snippets/Style_pages_based_on_categories
Which can be found here: http://wiki.engineeredarts.co.uk/MediaWiki:Common.js
Extension should be implemented server-side to avoid the delay between loading the page and the colour changing.
Haven't yet found an extension to do this. 
This is close, and could be suitable via templates: https://www.mediawiki.org/wiki/Extension:AddBodyClass
