How do I set the color theme for the GUI in PCB Editor 17.4 from a "dark theme" to a "light theme" or vice versa? I was able to do this in Capture 17.4 but cant find out how in PCB Editor 17.4.



  1. Select the menu items:  Setup > User Preferences. Your selection opens the User Preferences Editor.  
  2. Expand the UI folder and General sub-folder.

  3. Click the allegro_theme drop menu arrow and select light or dark to specify your theme selection.
