programming flash

basically when you load the .swf it changed everytime u re-load it , i want it to keep on changing even when the user hasnt reloaded the image

onClipEvent (load) {
for (i=1; i<5; i++) {
_root[“r”+i+“New”] = random(255);
_root[“g”+i+“New”] = random(255);
_root[“b”+i+“New”] = random(255);
_root[“b”+i+“New”] = random(255);
}
}

onClipEvent (load) {
myNum = _name;
}
onClipEvent (enterFrame) {
_root[“r”+myNum+“Diff”] = _root[“r”+myNum+“New”]-_root[“r”+myNum+“Old”];
_root[“r”+myNum+“Change”] = _root[“r”+myNum+“Diff”]/10;
_root[“g”+myNum+“Diff”] = _root[“g”+myNum+“New”]-_root[“g”+myNum+“Old”];
_root[“g”+myNum+“Change”] = _root[“g”+myNum+“Diff”]/10;
_root[“b”+myNum+“Diff”] = _root[“b”+myNum+“New”]-_root[“b”+myNum+“Old”];
_root[“b”+myNum+“Change”] = _root[“b”+myNum+“Diff”]/10;
swatchColor = new Color(this);
swatchColor.setRGB(_root[“r”+myNum+“Change”]<< 16 | _root[“g”+myNum+“Change”] << 8 |

       _root["b"+myNum+"Change"]);
        _root["r"+myNum+"Old"] -= _root["r"+myNum+"New"]-_root["r"+myNum+"Change"];
        _root["g"+myNum+"Old"] -= _root["g"+myNum+"New"]-_root["g"+myNum+"Change"];
        _root["b"+myNum+"Old"] -= _root["b"+myNum+"New"]-_root["b"+myNum+"Change"];

}
