How to change Editor Background

Trying to change the editor background in 2020 to match the 2019 grey style. The black and white style hurts my eyes. I’d like to switch to the old style but cant seem to find the right setting to adjust

Should be in Edit → Preferences → General → Editor Theme, with options for Light or Dark.
