Theme color changes for Oblivion

I’m using the Oblivion theme and trying to customize the colors. I was able to change some of the colors using the Theme Options but there are still elements to the page that I cannot change.

I am not CSS savvy and bought this theme because it showed lots of different colored themes to choose from. I can’t find any of them.

Right now the elements I can’t change are the footer and the menu drop down colors. How do I do this?
