Hi there,
The area below your footer should only be visible on pages where the content is shorter than the screen height. The color below the footer will be whatever color you have set for your body area.
There’s no way to apply a different color below the footer unfortunately without being super hacky.
One option is to stick your footer to the bottom of the screen: http://generatepress.com/forums/topic/how-to-stick-the-footer-at-the-bottom/
