User interface themes
The interface theme defines the appearance of windows, dialogs, buttons, and all visual elements of the user interface. By default, IntelliJ IDEA uses the Dark theme unless you changed it during the first run.
note
The interface theme is not the same as the color scheme, which defines the colors, fonts, and syntax highlighting for various text resources: the source code, search results, and so on.
In the Settings dialog (CtrlAlt0S) , select Appearance & Behavior | Appearance.
Select the UI theme from the Theme list:
Dark: IntelliJ IDEA default dark theme
Light: IntelliJ IDEA default light theme
Light with Light Header: default light theme with a light header
High Contrast: theme designed for users with color vision deficiency
Darcula: alternative dark theme
Click Get More Themes to install a custom theme as a plugin from JetBrains Marketplace
Optionally, select a color scheme from the Editor color scheme list.
The default color scheme for the current theme is indicated in the list.
tip
Sync with OS is not yet supported on Linux. You can track the progress and leave your feedback in IJPL-54591.
Select Sync with OS to let IntelliJ IDEA detect the current system settings and use the default dark or light theme accordingly. If your OS is set up to auto-switch between day and night modes, the IDE will automatically toggle between light and dark themes too.
It is also possible to create your own UI themes for IntelliJ IDEA and customize the built-in themes. For more information, refer to IntelliJ Platform SDK Documentation.
Press Ctrl0` or select View | Quick Switch Scheme from the main menu.
In the Switch popup, select Theme, and then select the desired interface theme.
You can map the Theme action to your preferred key combination.
Thanks for your feedback!
