Custom UI Themes

Beginning with the 2019.1 release, custom UI Themes are supported by IntelliJ IDEA. Custom UI Themes give designers control of the appearance of built-in IntelliJ IDEA UI elements. The UI Themes available for download illustrate the creative possibilities.

Creating a new UI element for a plugin is distinctly different than Custom UI Themes.

Note

Custom UI Themes are available beginning in version 2019.1.

This section discusses creating and customizing UI Themes:

• Creating UI Themes
• Customizing UI Themes
• Adding Editor Schemes and Background Images

For plugin developers, Exposing Theme Metadata discusses the format of customization keys and information how to provide it to Theme authors.
