CLion 2024.1 Help

Colors and fonts

As a developer, you work with a lot of text resources: the source code in the editor, search results, debugger information, console input and output, and so on. Color and font styles are used to format this text and help you better understand it at a glance.

CLion lets you choose between configurable color schemes that define colors and fonts used in IDE text.

You can use a predefined color scheme or customize it to your liking. It is also possible to share schemes.

Select a color scheme

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme.

    Alternatively, you can select a scheme on the Appearance & Behavior | Appearance page.

  2. Use the Scheme list to select a color scheme.

    The default color scheme for the current interface theme is indicated in the list.

    Select the color scheme

    Click Change IDE Theme to navigate to the Appearance & Behavior | Appearance page in settings on which you can configure an interface theme.

Customize a color scheme

You can customize a predefined color scheme, but it is recommended that you create a duplicate for your custom color and font settings:

Duplicate a color scheme

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme.

  2. Select a color scheme, click the Settings icon, and then click Duplicate.

    Duplicate a color scheme
  3. (Optional) To rename your custom scheme, click the Settings icon and select Rename.

Edit font and color settings

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme.

    The settings under Editor | Color Scheme are grouped in sections.

  2. Expand the Color Scheme node and select the required section.

  3. Change the settings in the right-hand pane.

    You can change font style, add effects, and modify color settings. To change the colors, click the field with color code. The color picker popup opens allowing you to choose the color as you like.

    For example, you can change the unused code highlighting:

Semantic highlighting

By default, the color scheme defines syntax highlighting for reserved words and other symbols in your source code: operators, keywords, suggestions, string literals, and so on. If you have a function or method with many parameters and local variables, it may be hard to distinguish them from one another at a glance. You can use semantic highlighting to assign a different color to each parameter and local variable.

Enable semantic highlighting

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme | Language Defaults | Semantic highlighting.

  2. Select the Semantic highlighting checkbox and customize the color ranges if necessary.

Share color schemes

If you are used to a specific color scheme, you can export it from one installation and import it to another one. You can also share color schemes with other developers.

Export a color scheme as XML

CLion can save your color scheme settings as an XML file with the .icls extension. You can then import the file to another installation.

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme.

  2. From the Scheme list, select a color scheme, click The Settings icon, then click Export and select IntelliJ IDEA color scheme (.icls).

  3. Specify the name and location of the file and save it.

Export a color scheme as a plugin

The plugin can be uploaded to the plugin repository for others to install. This format has several benefits over an XML file, including metadata, feedback, download statistics, and versioning (when you upload a new version of the plugin, users will be notified about it).

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme.

  2. From the Scheme list, select a color scheme, click The Settings icon, then click Export and select Color scheme plugin .jar.

  3. In the Create Color Scheme Plugin dialog, specify the version details and vendor information. Then click OK.

Import a color scheme

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme.

  2. From the Scheme list, select a color scheme, click The Settings icon, then click Import Scheme.

Fonts

Customize the default editor font

This font will be used and inherited in all color schemes by default.

  1. Press Ctrl+Alt+S to open settings and then select Editor | Font.

  2. Select the font from the Font list.

    The Font settings page
  3. Click Apply to save the settings.

For more information, refer to Font.

Customize the color scheme font

Set a different font for your current scheme if necessary.

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme | Color Scheme Font.

  2. Select the Use color scheme font instead of the default checkbox.

The Color Scheme Font settings page

For more information, refer to Color Scheme.

Customize the console font

By default, the text in the console uses the same font as the color scheme. To use a different font in the console:

  1. Press Ctrl+Alt+S to open settings and then select Editor | Color Scheme | Console Font.

  2. Select the Use console font instead of the default checkbox.

Install a new custom font

CLion can use any font that is available in your operating system or in the Java runtime that is used to run CLion. If you want to add another font, you need to install it in your OS, and CLion will discover it after a restart.

  1. Download the desired TTF font package and unzip it to extract font files (.ttf ). For the font to work correctly, it should have at least 4 files: Normal, Bold, Italic, and Bold Italic.

  2. Depending on your operating system, do one of the following:

    Select all font files, right-click the selection and choose Install.

    Select all font files, double-click the selection to open the Font Book preview, then click Install Font at the bottom.

    Unpack fonts to ~/.local/share/fonts for the current user or to /usr/share/fonts to install fonts system-wide, and then run fc-cache -f -v.

  3. Restart CLion and then select the installed font on the Editor | Font page of settingsĀ  Ctrl+Alt+S.
