The fundamental problem is how terminal colors are specified. The old non-color terminals had brightness and bold. The first color terminal, setting the standard, had just 8 colors without brightness control. Put those together, and you have 16. The result is not what you'd like. You'd really like to specify an overall scheme (light on dark, or dark on light) and then hues for each character displayed. That'd let you see green on green just fine. It wouldn't even be possible for the foreground and background to be identical, because one would be light and one would be dark. I suppose that switching everybody over might not be as hard as I thought at first. Considering systemd, it only takes a manager at Red Hat to force a new standard. I sure would appreciate it.
