The Headertabs extension is a rather interesting device, as what it does is use jQuery to rewrite the page in the browser to convert the headers in the DOM into jQueryUI tabs. This is why it doesn't play nice with a lot of custom formatting that users like to put on their pages. Since it's client-side JS, and we don't allow users to add custom JS to their pages for security reasons, there's not really anything that can be done by a user.
It is possible to extend it the plugin with custom CSS styles ("skins"), either loaded in the site's common CSS or from files on the server. However, this is something that'd have to be set up for everyone in advance, and I don't think anyone wants to get into the business of modifying the site CSS every time someone wants a small tweak to the colors of their tabs.
As a side note, I'm aware of Extension:CSS and Extension:NewPageCSS for page-specific stylesheets. These introduce some technical wrinkles, such as disabling some of our caching because of how they work, but they also introduce the possibility of enterprising users rewriting the entire site style in their pages. CSS loaded on a page can, for instance, eliminate parts of the UI, move around UI parts, and generally make the site harder/impossible to use, and that's why we've never installed these extensions. For that level of control, I recommend hosting the character page elsewhere; part of the value of the RPC wiki is that there's a somewhat unified interface outside of the content area.
