Please do not use colors in rc. Escape-sequenced colors make
unacceptable assumptions about the user and syslogd strips
escape sequences anyway, so it would be of no use to logged
consoles. Serial consoles introduce other problems with buggy
escape handling in third-party terminal programs. A good text
layout and descriptive status messages do far more for clarity
and readability than any use of color ever can.
Let me add to that. About 10% of the male population has some
color vision problem. Mine is a bit more than others. Everytime
I get called to work on a Linux system, I have to go in and disable
the colors as the reds and other colors become very hard to see
against a dark background. The problem is the luminance value of
colors such a red is quite low compared to others. That's one of
the reasons why fire-trucks in this area are lime-green, as red
trucks disappear into the blackness at night.
If you add color make sure it is a user selectable option
and not turned on by default. IMO everything you need to admin a
system needs to be able to run on something as lowly as a pure
serial terminal as the above poster notes.
Ok. So I've received mass amounts of mail regarding this, and most of it
has been positively in favor of having the option to enable the
rc_fancy, and then an additional option to turn on coloring, with the
default to be non-colored but still rc_fancy="YES" which should work ok
on serial and other terminals (it did for me).
I completely agree about all the coloring comments, and terminal issues.
I personally think it should be an available option, easily enabled or
disabled at will.
I've put up an updated version, with many changes. This version
includes optional coloring (with rc_fancy_color="YES" in rc.conf),
better checking, cleaner coding, and no loops. This version is *much*
more refined than the others - thanks for all the hints everyone!

Looks like this version does something strange - from an xterm, the
spacing is correct, but from console, it doesn't do anything with the
\033[71G in the echo. I've played with term types, but can't seem to
make it act the same under console as it does in an xterm.
Anyone know the issue?
