How to use the pusher.color function in pusher

Boardroom.show = function(cb){
    startDate = new Date();
    lastTime = Date.now();

    $("#boardroom").css({"visibility": "visible"});
    for(var i = 0; i< 20; i++){
        locationAreaColors[i] = pushercolor('#00eeee').blend('#ffcc00', i/20).hex6();
    }

    //animate();

    // render the other elements intro animations

    $(".footer-bar").delay(1000).animate({"margin-top": "0"}, 500);

    $("#globe-footer img").delay(1500).animate({"opacity": "1"}, 1000);

    $("#globalization").delay(600).animate({
        top: "0px",
        left: "0px",
        width: "180px"
    }, 500);
