dash, POSIX, or C89 have nothing to do with colors, it depends on
your terminal whether it interprets certain escape sequences as
color attributes.
Ahh. Ok.
You can print arbitrary bytes in a portable way (i.e. as
specified by POSIX) by using octal notation, e.g. escape is 033
in octal:
printf "\033[1;32mpassed\033[0m\n"
Understood; I get how this all fits together now.
Thanks for your example and explanation!
