In theory, most tools should be smart enough to completely disable color when TERM=dumb. Unfortunately, it seems that GNU ls (with --color=auto) just checks isatty and assumes that all reasonable ttys can support at least 16 colors (which is probably a fair assumption these days, but IMHO "dumb" means "no really, I can't do anything other than clearing the screen, don't try to get clever with me" rather than "just assume I'm a vt100 or whatever"). I have not tried exa.

Surely "dumb" means "I can't do anything other than printing characters - not even clearing the screen"?

AIX login assumes you can clear any screen with enough linefeeds.

Sounds like a waste of paper :)
