I used to match my terminal theme to CGA colors (DOS ANSI), the lighter colors on VGA default aren't quite the same (wikipedia screenshot). You can get the right color codes from something like Pablo or Moebius. It's a bit of a pain, and I'm honestly surprised more terminals/editors don't have a "DOS ANSI" theme option that matches those color codes. I have a reg file saved to do it for the old Windows console, but dropped windows a few years ago, and even then was using the new terminal.
