Run functions when pressed enter?

Hi everybody, while playing with the zsh prompt, I had an idea, since, having only one color, is kind of boring...(:D) Why not randomize the color?

And so I did:

The problem, as you can see is that it only gets one color everytime zsh is called, and I want to have it different everytime!

So, here's my prompt, (and the functions):

random_color(){
    random -e 7
    case $? in
        0) color=$white;;
        1) color=$green;;
        2) color=$blue;;
        3) color=$cyan;;
        4) color=$magenta;;
        5) color=$yellow;;
        6) color=$red;;
    esac
}
random_color
number_col="%(?.$green%?.$red$?)$reset"
path_col="$color%d$reset"

PROMPT="┌─[$number_col]─[$path_col]
└╼ "

Any ideas, anyone?

Are you calling that with the zsh precmd  function? It runs each time just before the prompt is refreshed, much like bash's PROMPT_COMMAND
