how to change the background color?

My site is https://www.thesbeauty.com. Now the background color for my store is white. I want to change the background color left outside my store to pale green. Which code should I change in the stylesheet? Thanks!

In the following file

includes/templates/classic/css/stylesheet.css

change the background-color to the colour you want.
