   You can also easy tween this filter by using the CalculateFinalFlatArray() method of the AdjustColor. I made a simple example here for those who are interested:

   package
   {
   import flash.display.*;
   import fl.motion.AdjustColor;
   import flash.filters.ColorMatrixFilter;
   import fl.transitions.*;
   import fl.transitions.easing.*;

   public class myClass extends Sprite
   {
   private var mySprite:Sprite;

   public function myClass()
   {
   var mySprite:Sprite = new Sprite();
   mySprite.graphics.beginFill(0xFFFF00);
   mySprite.graphics.drawRect(0, 0, 150, 100);
   mySprite.graphics.endFill();
   addChild(mySprite);

   var adjColor:AdjustColor = new AdjustColor();
   adjColor.saturation = 0;
   adjColor.contrast = 0;
   adjColor.brightness = 0;
   adjColor.hue = 0;

   colorTween = new Tween(adjColor, “hue”, None.easeIn, 0, 125, 2, true);

   colorTween.addEventListener(TweenEvent.MOTION_CHANGE, updateColors);
   }

   private function updateColors(e:TweenEvent):void
   {
   var cmf:ColorMatrixFilter = new ColorMatrixFilter(adjColor.CalculateFinalFlatArray());
   mySprite.filters = [cmf];
   }
   }
   }

   I hope it’s useful for someone

   ooops.. little correction.. just declare the AdjustColor under the sprite so it will be known in the function updateColors:

   private var mySprite:Sprite;
   private var adjColor:AdjustColor;

   and in the function myClass:

   mySprite = new Sprite(); // No need to redeclare
   adjColor = new AdjustColor();

   Sorry for the mistake, I just wrote the whole thing in this textarea here, I guess my brain was locked in scramble mode :-p
