Ideally, colors shouldn't be hard-coded via print_theme_stylesheet. I am kind of a newbie too so excuse my jumping in, but I think it would be better to do something like:

.module-header a, .module-header a:visited {
      color: $*color_module_title;
     } 

.entry-title a:visited {
      color: $*color_entry_title;
     }
