Darkening a movieclip in flash

Question

I have a container movieclip that's white. At the end of my game, I want the movieclip to turn black but gradually, creating an image effect from white to black. Basically I want the movieclip to darken and keep darkening until the movieclip is completely black, and then the darkening stops. Any ideas on how to accomplish this?

You can try a color transform.

var fade:Number = 1.0;
var fadeAmount:Number = 0.01;
var timer:Timer = new Timer(33);
timer.addEventListener(TimerEvent.TIMER, darken);
timer.start();


function darken(e:TimerEvent):void 
{
    fade -= fadeAmount;
    if(fade < 0.0) {
        fade = 0.0;
        timer.stop();
    }
    movieClip.transform.colorTransform = new ColorTransform(fade, fade, fade, 1.0, 0, 0, 0, 0);
}
