Configuring Colors and Fonts
With CLion, you can maintain your preferable colors and fonts layout for syntax and error highlighting in the editor, search results, Debugger and consoles via font and color schemes.
CLion comes with a number of pre-defined color schemes. You can select one of them, or create your own one, and configure its settings to your taste.
It is important to mention the Language Defaults settings page, which contains the settings that are common for all the supported languages. It's enough to change one of the settings there, and then inherit this setting from the defaults.
To configure colors and fonts
- In the Settings/Preferences dialog (Ctrl+Alt+S), click Color Scheme under Editor. The Color Scheme page opens.
- Select the desired scheme from the Scheme name drop-down list.
- Under the Color Scheme node, define the font families used in the editor and in the console. When you open the Font page, or Console Fonts under the Color Scheme node, CLion displays the Editor Font area where you can configure the primary and secondary fonts, their size and line spacing.
- Under the Color Scheme node, open the corresponding pages to configure specific color preferences for the supported languages and CLion components.

Changing the language defaults
The node Language Defaults is actually language-agnostic. It contains the settings that are common to the majority of the supported languages (keywords, dots, commas, parenthesis etc.)
Select the node Language Defaults, and in the list of textual components, select Keyword. The background of the keywords is white; let's make it slightly.
To do that, select the checkbox to the left of the field name Background, and then click the white swatch. The Color Picker opens — all you need to do is select the desired color and click OK:
So far, the changes to the language defaults are made; now let's look how they can be inherited.
Example: changing font for C++
Click the C++ node.
In the list of language components, select Keyword. As you can see, keywords now have the background of the above selected color:
It's important to note that the checkbox Inherit values from is selected!
Clicking the link below this checkbox leads you to the respective page under the Colors Scheme node, in this case to Language Defaults.
Next, clear Inherit values from, and define the desired font type using the Bold and Italic checkboxes. In this case, these textual components will change for the selected language only!
Observe the results in the preview pane.
What happens if there is a function with a long list of uniformly highlighted parameters? One can easily make CLion distinguish each parameter from the others using the semantic highlighting.

- In the list of the supported C/C++ components, choose Semantic highlighting.
- In the right-hand pane, select the Semantic highlighting checkbox:
- After that, all the parameters in a lengthy list will get the colors from the suggested swatches. If one is not happy with the suggested colors, click on a swatch to choose the suitable color.
