Design Bug? Background issue…

Hey everyone!
First of all, I am using the responsive directory theme….and I LOVE IT!

It is just perfect for me.

Here is the issue description:

As I am setting up a fetish directory site, I want to change my colors and styles. The thing is, that the red background on the content and footer area does not disappear, no matter what I try to change.
I am talking about the #dd3333 color on https://fetischadressen.com

What can I do to change that to white?
SI tried to set the colors all to white, just to see what happens (In the left side design configurator as well as within the CSS file) and it still does not change to white.

Thx for help.

Cheers
Michael
