Working on color wheel i hope it looks good.

Code Snippet that will be used to convert color codes from RGB to Hex and Hex to RGB

function HEX2RGB ( HEX:Number ) {
 var RGB:Object = {
 r:Number = (HEX & 0xff0000) >> 16,
 g:Number = (HEX & 0x00ff00) >> 8,
 b:Number = HEX & 0x0000ff }
 return RGB;
}

function RGB2HEX ( RGB:Object ) {
 return (RGB.r << 16) + (RGB.g << 8 ) + RGB.b;
}

How to get Hex form ARGB

package druva {
	import flash.display.Sprite;

	public class ColorUtils extends Sprite {
		public function ColorUtils() {
		}

		public static function ARGBtoHex(a:Number, r:Number, g:Number, b:Number) {
		return (a << 24 | r << 16 | g << 8 | b);
	}

	}
}
