Nice! That should come in useful for anyone using different types.
Fortunately, they all use the same 'xterm*' entries in the .Xresources
file, so other bits of behavior, etc. don't need to be adapted.

Somewhat in the same vein, I like to distinguish between consoles 1-3 by
setting different colors (I also use red, but it's reserved for root
logins). From my ~/.bash_profile:

```
TTY=`tty`
[ ${TTY:5:3} == "tty" ] && {             # If not a console, bail!
    color=(x blue green magenta)         # tty's start at 1, arrays at 0...
    setterm -foreground ${color[${TTY#*y}]} -store
}
