Movie clip gradient tint code

Hi
I have animation (movieClip)which loads on my homepage.
Code:
import com.mosesSupposes.fuse.*;
ZigoEngine.simpleSetup( Shortcuts, PennerEasing );

head_mc._scale = 20;
head_mc._brightOffset = 50;
head_mc._rotation = 200;
head_mc.scaleTo(48, 2, “easeOutBack”);
head_mc.colorResetTo(100, 3);
head_mc.rotateTo(0, 2, “easeOutBack”);
[COLOR=“Red”]head_mc._tint = “#347BE4”;[/COLOR]

Rather than have just a tint to the movie clip I would like a gradient.
anybody know how I can achieve this.
