Hi guys!  
I’ve been playing around with AS2 under FlashMX 2004 Pro recently, and with prototypes in particular. I’ve seen several examples of prototyping (i.e. the Robert Penner’s color\_toolkit) that define proto in the Color Object.  
So I’ve come up with this easy script on Stage (myShapeMC is a simple square) :

```auto

Color.prototype.dummy= function(){
trace("into dummy");
}
var c:Color = new Color(_root.myShape);
c.dummy();

```

This produces the following error :

```auto

**Error** Scene=Scene 1, layer=Layer 2, frame=1:Line 5:
There is no method with the name 'dummy'.
c.dummy();

```

Am I missing something or is it simply impossible to add prototypes to the Color Object in ActionScript 2 ???

Thanks in advance…
