I am trying to change the color to the left and right of the content area of the Fashion Mosaic(grey) temp (from white to black) and leave the main content area white. I have tried using FireBug to locate this area with no luck and I don't think the Admin mode is made for this sort of thing??? It acts like the entire page back ground is white? Can someone please tell me what I am doing wrong and how I can get my sides black?

Thank you!
