So far, this is the only thing I’ve seen posted about customizing the hottags:

It doesn’t specifically address the colors, just the size, of the tags. I imagine, since the style tag is with a font-size in it, like this:

 style="font-size: 9pt;"

that you could make a plugin that did something where if the font size is between a and b, add “font-color: #whatever;” and if it’s between b and c, add “font-color: #whatever2;” etc.

I think this would be pretty interesting. I can see where this code would need to be added in bb-includes/template-functions.php, but that’s a really bad idea (modifying core files) – so, a plugin is a much better idea.
