I’m trying to make a color utility class the with adjust color based on their hue (color), saturation (amount of white), and back values.

Does anyone have any idea how – using bitwise operators – to increase the saturation, back or change the hue… something like this:

```auto

public function hue( hex:uint, amount:Number)uint
{

return newcolor
}

public function sturation( hex:uint, amount:Number)uint
{

return newcolor
}

public function black( hex:uint, amount:Number)uint
{

return newcolor
}

```
