Changing Background Color For Single Page

Hey guys, great theme, well worth the purchase!

I’m having an issue though with the background color. I have set the background color for the whole site and it looks great, however one of my pages requires a black background instead, I’m having a heck of a time figuring out how to accomplish that. I downloaded two different plugins but they didn’t work with this theme so I was hoping to get some insights here. Thanks!
