public class changeColor extends Sprite {
        private var mySpr:Sprite;
        public function changeColor() {
            super();
            mySpr = new Sprite();
            mySpr.graphics.beginFill(0xFF0000, 1);
            mySpr.graphics.drawRect(0, 0, 100, 100);
            mySpr.graphics.endFill();
            mySpr.addEventListener(MouseEvent.CLICK, action);
            addChild(mySpr);
        }
        public function changeSprColor(inputColor:uint):void {
            var myCt:ColorTransform = new ColorTransform();
            myCt.color = inputColor;
            mySpr.transform.colorTransform = myCt;
        }
        private function action(e:MouseEvent):void {
            changeSprColor(0x00FF00);
        }
    }
