i am using the custom field template and until now i can make nice use of it.
unfortunately when i use the shortcode [cft format=2] and then display the page it gets rendered without the background color. this seems to be a bug..
normally the background color is defined at the "page" class. when using the above mentioned shortcode the "page" class already ends after the navigation-bar and i think that's the reason why the background color in the page is not rendered..
