...Um, yeah, like I asked, are different colours necessary considering they've [the templates] all, AFAIcan tell, been given pretty much the same style? If the answer is yes, then only the one class would suffice. I'm sure you could even get away with using a copy of .wikitable; like I say, you're not going to lose any more variety, since making them all black has removed it all already.

Am I right in thinking the only table-like templates are those in category:navigation templates, category:copyright templates and category:infoboxes? It's hard to tell since you don't have a root category:templates.
