Change font color off the post titles

Could you supply the custom css for changing color of the titles and headers associated with posts: both the post titles themselves and the page header on a page with a given category of posts? I have the following code on my test site that takes care of page and widget headers, but it's not working for posts. .entry-header, .widget-title, .entry-title{ color: #604187; } See especially the following pages: http://everygoodgift.org/wptest/category/news/ http://everygoodgift.org/wptest/category/events/
