If you want to add one color to another and then set a movie clip to that tint I have provided the function below. The idea is to sort of mix colors in the way paint is mixed here is how you do it:

{codecaption width="800"}

function addColorToLayer(layerToTint:DisplayObject, hexVal:String):void{
           var colorTransform:ColorTransform = new ColorTransform();
           var newColor:uint;
           var rgb:RGB = new RGB();
           var rgb2:RGB = new RGB();
           var rgb3:RGB = new RGB();

          rgb.r = parseInt( "0x"+hexVal.charAt(0)+hexVal.charAt(1) );
           rgb.g = parseInt( "0x"+hexVal.charAt(2)+hexVal.charAt(3) );
           rgb.b = parseInt( "0x"+hexVal.charAt(4)+hexVal.charAt(5) );

           rgb2.r = layerToTint.transform.colorTransform.redOffset;
           rgb2.g = layerToTint.transform.colorTransform.greenOffset;
           rgb2.b = layerToTint.transform.colorTransform.blueOffset;

           rgb3.r = int( (rgb.r*.1)+(rgb2.r*.9) );
           rgb3.g = int( (rgb.g*.1)+(rgb2.g*.9) );
           rgb3.b = int( (rgb.b*.1)+(rgb2.b*.9) );
           // convert the new number to a hex and then an int and transform the mc
           newColor = (rgb3.r << 16) | (rgb3.g << 8) | rgb3.b;
           layerToTint.changeColor(newColor);
       }
