User interface themes
The interface theme defines the appearance of windows, dialogs, buttons, and all visual elements of the user interface.
Change the UI theme
In the Preferences dialog (Ctrl+Alt+S), select Appearance & Behavior | Appearance.
Select the UI theme from the Theme list:
IntelliJ Light: Traditional light theme for IntelliJ-based IDEs
macOS Light: OS-specific light theme available as a bundled plugin
Darcula: Default dark theme
High contrast: Theme designed for users with color vision deficiency
Select Sync with OS to let AppCode detect the current system settings and use the default dark or light theme accordingly.
It is also possible to create your own UI themes for AppCode and customize the built-in themes. For more information, see IntelliJ Platform SDK Documentation.
