Page Background Color Question

Hello Everyone,

I was wondering how to change my page background color. I have changed the background color as well as my content box colors, but would still like to change the color of my page. If you look at my site https://www.myequineconnections.com you will see the area that is still white that is the area I am wanting to change the color of. Any help is greatly appreciated. Thank You In Advance. I am using the responsive classified theme with the New Day Child Theme.
