I'm using the WebStorm IDE. I decided to change the theme, everything worked fine except for the active bar, the color theme of the active bar does not change:
How to solve this problem?
You have changed the Color Scheme only -- it affects Editor (syntax colors) mainly + VCS File Status and some other aspects.
To change the whole window you need to change GUI Theme at Settings/Preferences | Appearance & Behavior | Appearance | Theme
(HINT: search field helps a lot in narrowing it down).
You can also do that via View | Quick Switch Scheme...
(which is a much faster way than going via Settings screen)
