I have installed Material Theme UI and it made my IDE blackish. Later I decided to remove and and removed plugin. Unfortunately, this didn\'t give default colors back, some part
From the material-theme-jetbrains repo:
File Colors stuck after uninstallation The File Status Colors feature is also a feature that sticks outside of the realm of the plugin as it modifies the IDE itself. Therefore when uninstalling/disabling the plugin the colors will stuck.
If you want to reset to the default colors, open the Settings at Version Control -> File Status Colors in 2017.3+. In previous versions, you will need to go to the config directory and delete the _@user_Darcula.icls color scheme manually.
