For the record, the man page available on all of the Debian systems we
have claim to be "GNU coreutils 8.28" from October 2017 and includes
this verbiage:
[start]
...
--color[=WHEN]
colorize the output; WHEN can be 'always' (default if omitted),
'auto', or 'never'; more info below
...
Using color to distinguish file types is disabled both by default
and with --color=never. With --color=auto, ls emits
color codes only when standard output is connected to a terminal. The
LS_COLORS environment variable can change the set‐
tings. Use the dircolors command to set it.
...
[end]
To join this thread back into one... I think the problem is that I've
worded things terrible, so you misunderstand. The default value is
--color=auto *if you've requested colors* (-G/environment), and
--color=never otherwise. Doing otherwise is, IMO, a POLA violation in
itself, because FreeBSD turns on colors with environment variables and
has for 18 years now.
