I think you can do this by creating enum filed in category & link (if you want to display certain category also with different link colors and links/listings also with different link color). Name is SpecialColor and for options have Yes/No.

Now using if/elseif/endif tags in subcategory.html & link.html have different CSS tags for SpecialColor Yes & Special Color No.

Hope this helps.
