una cosa del genere????
codice:
MovieClip.prototype.fadeColor = function (finalColor, finalAlpha, speed, callback) {
	this.percentage = 0;
	clearInterval (this.fadeInt); 
	this.tmpColor = new Color (this);
	this.deltaAlpha = finalAlpha - this._alpha;
	this.startAlpha = this._alpha;
	this.fade =  function (target_MC) {
		if (target_MC.percentage >= 1) {	
			target_MC.startColor = finalColor;
			target_MC._alpha = finalAlpha;
			clearInterval (target_MC.fadeInt);
			callback ();
		} else {
			target_MC.percentage += speed;
			target_MC.tmpColor.blendRGB(target_MC.startColor, finalColor, target_MC.percentage);
			if (target_MC.deltaAlpha != 0) {
				target_MC._alpha = target_MC.startAlpha + (target_MC.deltaAlpha * target_MC.percentage);
			}
		}
	}
	this.fadeInt= setInterval (this.fade, 40, this);
}
//	Hide the function and the related properties to the for in loops
ASSetPropFlags(MovieClip.prototype, "fadeColor", 1, 0);


Color.prototype.blendRGB = function(c1,c2,t){
	if (arguments.length == 2){
		t = c2;
		c2 = this.getRGB();
	}
	if (t<-1) t=-1;
	else if (t>1) t=1;
	if (t<0) t=1+t;
	c1 = c1.HEXtoRGB();
	c2 = c2.HEXtoRGB();
	var ct = (c1.rb+(c2.rb-c1.rb)*t) << 16 | (c1.gb+(c2.gb-c1.gb)*t) << 8 | (c1.bb+(c2.bb-c1.bb)*t);
	this.setRGB(ct);
	return ct;
};

Number.prototype.HEXtoRGB = function(){
	return {rb:this >> 16, gb:(this >> 8) & 0xff, bb:this & 0xff};
};
richiami così per i tuoi clip
codice:
//	PARAMETERS
//	finalColor = the destination colour
//	finalAlpha = the destination Alpha
//	speed = values admitted are between 0 and 1 (ex. 0.05, 0.10 or 0.15)
//	callback = optional function to be called at the end of the fading

//	USAGE
//       create a clip named "myMovieClip_mc" and the buttons "sample1_btn" and "sample2_btn"
//       attach the following code to frame 1

//	set the starting color (only the first time);
//	if not set, the default is black
	myMovieClip_mc.startColor = 0x009933

//	set callback functions to be called when fading is finished
	function test () { 
	trace ("fading finished"); 
	}
	
//	change the movieClip to a semi-transparent yellow	
	myMovieClip_mc.fadeColor (0x009933, 50, .05, test); 
	
//	change the movieClip to an opaque azure, slowly
	//myMovieClip_mc.fadeColor (0x0191C7, 100, .02, test);
Ho notato che il forum nel codice ha messo una faccina
al posto della faccina vanno i : e poi ( di default il forum mette la faccina
