Yes. To the OP:

In zsh, you could do it like this in .zshrc (it'll be
similar in bash). I have a sort of similar setup [1],
only I have some other stuff there as well, *and* I
don't want those labels, so I provide them here so you
can compare directly to this screenshot [2], to see how
it works.

CURRENT_VT=`tty`
if [[ ${CURRENT_VT[6]} == "p" ]]; then
    if [[ `uname` == "SunOS" ]]; then
        # on a remote SunOS/Solaris system:
        # here, also  setup aliases and so forth
        # used on that specific machine
        export VT="Sun"
        PROMPT_VT="%K{red}%F{yellow}$VT%f%k"
    elif [[ $TERM == "screen" ]]; then
        # I always use tmux both in the Linux VTs and
        # on top of urxvt (the same as you use) -
        # confusingly, this is called "screen"
        export VT="tmux"
        PROMPT_VT="%F{red}$VT%f"
    elif [[ $EMACS == "t" ]]; then
        # Emacs
        export VT="emacs"
        PROMPT_VT="%F{red}$VT%f"
    fi
else
    # this will be the Linux VTs *without* tmux
    export VT=${CURRENT_VT: -1:1}
    PROMPT_VT="%F{red}$VT%f"
fi
PROMPT=" %B$PROMPT_VT %F{cyan}%(4~|../|)%3~%f%b "
