How to paint on laeyr?

I created few layers in IDE Animate with some graphic.

How can I paint Share on one of them layer before other layers?

var mc = new createjs.MovieClip();

var child1 = new createjs.Shape(new createjs.Graphics().beginFill("#ABC").drawRect(0,0,600,600);

mc.addChild(child1);

this.parent.addChild(mc);
