[FMX] Dragging and Dropping a duplicate clip

Hi, I’m creating a drag and drop movieclip to colour a different movieclip. I need to duplicate the first instance so as the original stays in the same place (on the pallette), and then the dragged one can be removed after it has been dropped into the area. This is the script for the dragging and dropping of the original instance, but I can’t figure out the duplication/removal part:

on (press) {
startDrag("_root.pallette1");
this._alpha = 70;
}
on (release) {
stopDrag();
if (eval(_root.pallette1._droptarget) == _root.one) {
var colorful = new Color("_root.one");
colorful.setRGB(0x0066CC);
}
}

Can anyone help, please?
Cheers
