How to match home widget colors in Responsive theme to body

Hi there,

Trying to match the color in the interior of my home widget boxes to the cost body color. I was able to kind of do it for the footer but there is still a white box that surrounds..sigh. There is already custom CSS that may be over riding but I'm not knowledgeable to know if it or not.
I did visit the tutorials but nothing I inserted made a difference.

Thank you ????
