As of today's change, to return non-existent categories to their former color, simply add: .newcategory { color: #CC2200 !important; /* or your color of choice */ } Not every wiki uses #C20 for their red links. If you want to add this globally for dynamically setting the category link color to the red link color of each wiki then add this to JS. $(function { $('.newcategory').addClass('new'); });
