I rarely work with the default X-cart install anymore, but to my knowledge the CSS file controls all of the colors in the site, there should be no hard-coded colors in there. Webmaster mode will tell you exactly which template is which, and then you can go into the template to find out what styles are being called. Firebug is a nice tool to use on any site to get right to the CSS in question, but not needed to edit the X-Cart templates. You won't find any HEX colors in the templates, it is all in the CSS. It is just a matter of finding out what class each item is calling, which is why I suggested Firebug.
