Change Skin/Background Color Photolux theme

Hello,

I am working on a site using the themeforest Photolux theme and cannot seem to figure out to how to make the background of my theme white. I am trying to get the entire site white (header, body, background, and footer). I think I would have to have an additional Css to adjust the the color to have everything the same color. I am very new to coding and to css so if anyone could help that would be great!
