Does anyone know how to create two new colours (highlight and shadow) based on one colour in ActionScript 3? So, if I have red (0xFF0000), I will get a light red and dark red too?

I have no idea. Thanks!

To get Highlight (lightness) you increase each R, G and B equally by same amount (with maximum at 255 or 0xFF). In your case Red is already at its maximum so increase both Green and Blue by same amount (eg do a = 128 on each of those channels).

To get Shadow (darkness) you decrease each R, G and B equally by same amount (with minimum at 0 or 0x00). In your case both Green and Blue are already at their minimum so just decrease only Red by x amount (eg do a -= 128 on Red channel).

In short:
Input = 0xFF0000 ... then Highlight = 0xFF8080 and Shadow = 0x800000.
