help: Color changing function

[GrimStrike]

Working in AS2 here trying to make a simple function to change the color of an object passed to it. I'm not getting a complier error but it's not working either.

import flash.geom.ColorTransform;

function color_change(color, mc) {
    var colorTrans = new ColorTransform();
    colorTrans.rgb = color;
    mc.colorTransform = colorTrans;
} 

I'm using the function call below:

change_color(0xFFFF00, _root.stabar); 

Thanks for the help.
