问题
I don't know what the name of this setting is. It's the (grayish) line that appears when you unfold a method, if, for, etc.. statement (see attached image). I want to change the color but can't find the option in the Android Studio 4.0 settings menu. Does anyone know what's it called and how to change it's color? thanks

Things have changed in android studio 4.0
In order to change the color of that indentation line do this
Go to File -> Settings -> Editor -> Color Scheme -> General
And inside that go to Editor -> Guides
You can set
- Indent Guide
- Indent Guide Selected
