Thanks, this looks much simpler.

In the non-quiet case, you will eval $say_color_, even though we know it to be bogus. I guess we need to make sure say_color_color is blank, though. The alternative would be:

  if test -z "$1"; then
    test -n "$quiet" && return
    say_color_color=
  else
    eval "say_color_color=\$say_color_$1"
  fi

I dunno if that makes the intent more clear or not. I am OK with it either way.
