Footer colors changed suddenly, how to revert back

The footer section that has three widget boxes on my Streamline theme blog https://2-copper-coins.com/ is now taking on the same white/gray background color as the body and primary sidebar. Originally it was the dark gray of the background and the text for our disclaimer was just a faint light gray on a dark background. At some point in the last few weeks it changed and I can’t figure out why.

Any ideas? I apologize if it’s obvious, I just played around with backgrounds enough that changing the widget background color doesn’t do what I’m trying to get it to do and I’m at a loss.

Thanks!
