title_body: font color not showing up on color Nook for new eBook epub
upvoted_answer: This could be either the Nook reading system or a problem in the code. The first thing to check is if your device is overriding publisher styles. Nook in particular is quite insistent about that, and will by default override all styles with its own. I don't recall exactly what menu that's in, but you should be able to find it.
  
  If that doesn't do the trick, then there's probably something up with the code&mdash;either the CSS that defines the styles or the XHTML that defines the structure that the styles are applied to. If you're still having problems after enabling publisher styles, feel free to update this post or make a new one with the relevant sections of code.
