I'd like to change the general background color of CLion (that is, outside of where you write code), but I have been unable to find a solution neither in the IDE itself nor online.
However, changing these colors should be possible, as switching the color theme does change them.
Here is an image of what I mean, I've marked the respective areas I would like to change the color of with a bright pink circled x:
Any help on where I could find these settings would be much appreciated.
EDIT: I already know where to change Fonts, text colors and the like, but I am looking specifically for the marked areas, changes for which do not appear under any of the Color Scheme Options.
You cannot customize the colors of the main interface except for choosing the Default and Darcula themes in Appearance and Behavior - Appearance
. What your and the other answer's screenshot shows are the EDITOR color scheme settings.
You can set a background image for the whole IDE in general in that settings tab, though. Make it completely opaque, the color you like, and that might do it.
