prova anche questo:

onClipEvent(load){
colore=new Color(this);
}
onClipEvent(mouseMove){
if (this.hitTest(_root._xmouse,_root._ymouse,false)&& !sopra){
this.colore.setRGB(0x0066cc);
sopra=true;
}else if(!this.hitTest(_root._xmouse,_root._ymouse,false )){
sopra=false;
}
if(sopra==false){
this.colore.setRGB(0x330099);
}
}
