Load movie and change color movie clip

Hello,

i wanna change color of mc. I have buttom Test and Parametri. In Test is movie testing.swf in Parametri you can change color of movie clips.
in file starttesting is make like this:

in layer1 is mcPlayer. In this mcPlayer are three layers, action, container and buttoms.
in action layer is this code:

mcButtonParametri.onRelease = function():Void{
 addWindow("mcPar");
}
mcButtonFoto.onRelease = function():Void{
 addMovie();
}
function addMovie():Void{
 
 var mcLoader:MovieClipLoader= new MovieClipLoader();
 mcLoader.loadClip("testing.swf",_root.player.container);
 
}
function addWindow(sLingage:String):Void{
 
 var nIndex:Number = this.getNextHighestDepth();
 var mcWindow:MovieClip = this.attachMovie(sLingage, "mcWindow"+nIndex, nIndex);
 mcWindow._x= -50;
 mcWindow._y= -100;
 
 mcWindow.mcOkvir.onPress = function():Void{
  this._parent.startDrag();
 }
 mcWindow.mcOkvir.onRelease = function() :Void{
  this._parent.stopDrag();
 }
 mcWindow.mcClose.onRelease= function():Void{
 this._parent.removeMovieClip();
 }
}

That is all.
All you can see in attache file

My problem is:
