I actually found it by doing a search through all pages, decided to try RED instead of the color code, and that came up with a ton of hits. So I used your advice and checked the page source, then searched for "color: red" and found it.
It's actually not part of the CSS files, it's hard coded in the pp-inc.php file on line 4581
$printdate = "<span style=\"color: red; font-size: 7pt;\"><b>$printdate</b></span>";
Once I changed that, all is perfect!
I thought I might post how I fixed it in case someone else has the same problem, it's not a CSS issue.
