One color, many objects

Hi!

I would like to know if there’s a way to change the color of various mc’s at the same time.

function colorit (mc) {
var colorful = new Color(mc);
colorful.setRGB(0xCC99FF);
}

coll_mc.onRelease = function(){
colorit (pre_mc, morf_mc)
}

What I need is that when onRelease change the color of some movie clips in the stage.

Thanks in advanced!
