This ActionScript 2.0 Class enables you to easily adjust the colour saturation of any Flash MovieClip during runtime. It requires Flash Player version 8 or above, and uses the ColourTransformationMatrix and some clever jiggery-pokery to adjust the RGBA channels of your MovieClips. In short, it’s sweet – and fills a gap in the built-in flash filter classes.
Have a look at this flash movie (below) to see the end result, all generated from the same MovieClip.
