Changing Background Color After Selecting A Different Color Sheme?

[Apury]

Hey there!

 

I'm using the default theme and changed the color sheme. However, I want to change the sides background color. I thought about going into photoshop and use the color picker to identify the hex code and find it that way in the global.css of my theme. However, that didn't work out. 

 

Any ideas where to look? I doubt that something like:

 

background-color: #ffffff !important;

 

Placed somewhere with "container" in it's name would do the job.
