I don't think he does (based on other things he's said before), but
he's right.  There isn't a built-in "red()" function because there are
hundreds (probably literally) of different terminals that can be
connected to a unix system and each has a (potentially) different set
of escape codes for controlling it.

That's in large part why Bill Joy created the "curses" library (with
the associated "termcap" database) back in the '70s.  The termcap
database stores the escape codes necessary to achieve the desired
results.  The end effect is that programs using the curses (or the
newer ncurses) library can be terminal agnostic, yet still work on all
the terminals supported by the termcap (or terminfo, if using ncurses)
database.

If you only need to support 1 particular terminal, then hard-coding
the escapes for it is manageable.
