Stage question

1

can the color of the stage be changed dynamicaly with out making a movie clip over it and using a color transfrom on that?

I don’t think so.

Creating a sprite, and using the graphics class to draw a rectangle of the required colour is the simplest method I know. (Unless you want to use a library symbol.)

var shape:Shape=new Shape();
stage.addChildAt(shape,0);
resize(null);
stage.addEventListener(Event.RESIZE,resize);
function resize(event:Event):void {
   shape.graphics.clear();
   shape.graphics.beginFill(color);
   shape.graphics.drawRect(0,0,stage.stageWidth,stage.stageHeight);
   shape.graphics.endFill();
}
