color hex RGB uint

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

To create donut shapes I have used shape with lineStyle+drawCircle+cacheAsBitmap drawed over original graphics using BlendMode.ALPHA. To browse RGB pelette there is a paletteColor() method that crawls all color spectrum based on position (0 to 1).
