RGP(custom character) contoling Color = Help!

Hi, I have a MC that has 2 layers: one has the outline and the other the shape. Then I have two buttons that chance the color of the MC. I want only want the “shape” layer to chance color. And because I want to able to make many more shapes in the MC, I don´t wan´t to have to make a MC out of each and every one… (see fla. for details)

Can anyone help me?

This is the button code i am using.
[LEFT]

 [LEFT]on (press) {
tellTarget ("/hair") {
color = new Color(_root.hair); 
    color.setRGB(0xF0520F); 


    }[/LEFT]
