Changing broder color of rectangle

1

i have a rectangle and i want to change its border colour on mouse over, i have found a way to make it work but that redraws the whole rectangle, i am wandering is it possible to only manipulate border colour without redrawing rectangle?

here is the code that works

import flash.display.Sprite;


var rect:Shape = new Shape();
rect.graphics.lineStyle(3, uint("0x666633"));
rect.graphics.beginFill(uint("231f1c"), 1);
rect.graphics.drawRect(0 , 0 , 60 ,10 );
rect.graphics.endFill();

var sprite:Sprite = new Sprite();
sprite.addChild(rect);
addChild(sprite);

sprite.addEventListener(MouseEvent.MOUSE_OVER , colorChange);
function colorChange(e:MouseEvent):void{
 rect.graphics.beginFill(uint("231f1c"), 1);
 rect.graphics.lineStyle(3,uint("0x6600"));
 rect.graphics.drawRect(0 , 0 , 60 ,10 );
 rect.graphics.endFill();
}
