2.8 adjust viewport background color

Can not find a way to change the value of my view-port so I can see my unselected mesh. Used to be a gradient in 2.79 but now I am lost how to do this. I see all kinds of stuff about cylces rendering background color but nothing about the viewport default.

Ok for some reason it it stopped scrolling its way down there

Wait, What was the answer??? :pleading_face:

Seriously, I feel like this program is just gaslighting me: I had been changing the viewport color using the World tab and just putting in whatever, but now that’s not work, and I have no idea why.
