Quick Tip: uint To 6 Digit RGB Hex
Shortest possible, simple / no looping method of getting hex string from color is:
var color:uint = 0x00ff00;
var hex:String = color.toString(16);
trace("00000".substr(0, 6 - hex.length) + hex);
// output 00ff00
trace("#00000".substr(0, 7 - hex.length) + hex);
// output #00ff00
