They would do nothing for me. High-color terminals and apps beak out of the 16-color limit. Changing my “color theme” when someone wants to look at my screen sounds like more work than typing NO_COLOR=1. If I need to look at someone else’s screen what can I possibly do about their choice of colors and terminal emulators?
