How to change the color of indentation guides in vscode settings?

The methods to modify the indented line color in VS Code are as follows: 1. Use the workbench.colorCustomizations setting item in the settings.json file to configure editorIndentGuide.background and editorIndentGuide.activeBackground (current line indented line color); 2. Use the shortcut key Ctrl to open the settings and click the {} icon, or open the settings.json file through the menu to edit; 3. Frequently asked questions include the theme not supported, the color format is incorrect, or the editor has not restarted. Checking these one by one can ensure that the settings take effect.

It is not difficult to modify the indentation line color in VS Code, but it is mainly achieved through the custom editor's color scheme. By default, the color of the indented line is determined by the current theme, but you can adjust it manually.

How to modify the color of the indented line

VS Code provides a setting item editorIndentGuide.activeBackground and editorIndentGuide.background , which are used to control the indent line colors of the current indent level and non-current level, respectively.

To modify the indentation line color, you can add the following configuration to your settings.json file:

 {
  "workbench.colorCustomizations": {
    "editorIndentGuide.background": "#333333",
    "editorIndentGuide.activeBackground": "#555555"
  }
}

In the example above:

• editorIndentGuide.background is the normal indent line color (not the current line)
• editorIndentGuide.activeBackground is the indent line color of the current line

You can choose the appropriate hexadecimal color code according to your theme.

How to find and edit settings.json?

If you are not sure how to open the settings file, you can do this:

• Shortcut key method: Press Ctrl , to open the settings interface, then click the {} icon in the upper right corner to enter JSON editing mode
• Menu method: Click the gear icon in the lower left corner → select "Settings" → click "Open Settings (JSON)" in the upper right corner

Or you can search for the "Preferences: Open User Settings (JSON)" command to open it.

Once the settings.json file is opened, you can paste the above configuration and save it.

Frequently Asked Questions and Notes

Sometimes the settings are not effective? There may be the following reasons:

• Theme does not support custom colors: Some old themes or community-developed themes may not fully support these color variables
• Color format error: Make sure to use a legal hex or rgba format, such as #ff0000 or rgba(255, 0, 0, 0.5)
• VS Code has not been restarted: Although the modification takes effect most of the time, the editor needs to be restarted occasionally

If you find that the indentation line color has not changed, you can try another topic to test it, or check whether the settings are overwritten by other plug-ins.

Basically that's it. Modifying the indented line color itself is not complicated, but details are easy to ignore, such as incorrect field names, incorrect color format, or the current theme restricts customization functions. As long as you pay attention to these points, you should be able to solve them.
