9.5.21 Artist: Unable to change Key Editor Background Color

Read a relevant topic and tried the solution given.

Preferences -> User Interface -> Custom Colors -> Editor Area Background

Although I change color at the menu, the change is not reflected in the key editor color, which remains a dark grey.
Any thoughts?

Make sure that you’re clicking the correct square.

Oh! I was clicking on the two boxes below that…

While we’re here, can someone post a picture of what that ‘Cycle Region’ colour in the editors does please.? Have never been able to get that to work… Maybe I’m just misunderstanding something.

All else is fine, when I’ve fiddled with the other colour options.

TIA
