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.
