Change Content area background

I am trying to change the content area on this theme to white. Its currently set to like an off white and some of my images dont look right because they have a white background so i need my Pages to be white so it flows smoothly.

Im using the evolv free theme, im just missing the CSS Code to change the background to white for all pages.

I dont have a link as my page is down until my sites down, but if you need to see what im talking about let me know and ill throw it up.

Thanks
