How to change indent guide color.
回答1:
You need to edit the color scheme file for the color scheme you are using, and find <key>activeGuide</key> and/or <key>guide</key> and change the hex color value in the <string> node below it to the value of the color you desire. See How do I edit the Solarized (Light) theme in Sublime Text 3 for details on how to make custom changes to color schemes.
