i think my usual inclination for colorization is to post-process
with sed. i haven't done it with scan output, but i do it
with a couple of different mail perusing scripts i've written.
leaving out the details, something like this:
color_init()
{
RED="$(printf \\033[1\;31m)"
GREEN="$(printf \\033[1\;32m)"
YELLOW="$(printf \\033[1\;33m)"
BLUE="$(printf \\033[1\;34m)"
PURPLE="$(printf \\033[1\;35m)"
CYAN="$(printf \\033[1\;36m)"
BOLD="$(printf \\033[1m)"
NORMAL="$(printf \\033[m)"
ESC="$(printf \\033)"
}
# make the Subject: and From: text stand out in red and blue
colorize()
{
sed \
-e 's/^\(Subject: *\)\(.*\)/\1'"$RED"'\2'"$NORMAL"'/' \
-e 's/^\(From: *\)\(.*\)/\1'"$BLUE"'\2'"$NORMAL"'/'
}
mhshow $msg | colorize
i guess you'd have to use a scan format which tagged the line,
and then sed might have to untag them as well as colorize them.
