[support] Pane Class based on a node field with Panels

Hello, I'm using panels for layout in my site. Some of my pages need to have special styling for the page title - ie different background. I tried using a context variable such as %node:content-type in the class field, but that doesn't seem to work. Any idea other than creating a variant for each header background. I wish panels worked like views where you could set a master and just change one setting in each "display/variant". Thanks Idan
