Я вот писал что-то для яркости и контраста ...

_global.MovieClip.prototype.addProperty ("_brightness", function ()
{
	if (typeof (this._brightness_) != "number")
	{
		this._brightness_ = 100;
	}
	return this._brightness_;
}, function (v:Number)
{
	this._brightness_ = v;
	var color:Color = new Color (this);
	var c:Number = 100;
	if (typeof (this._contrast_) == "number")
	{
		c = this._contrast_;
	}
	color.setTransform ({ra:c, rb:2.55 * v - 255, ga:c, gb:2.55 * v - 255, ba:c, bb:2.55 * v - 255, aa:100, ab:100});
});
