Flash 8 ColorMatrix Explained

Here are a couple sources I found really useful in understanding the ColorMatrix class:

http://www.adobe.com/devnet/flash/articles/matrix_transformations_04.html

http://chattyfig.figleaf.com/pipermail/flashcoders/2005-September/150592.html

These were simple and straightforward, unlike many of the articles on ColorMatrix that assume you have prior knowledge of matrices in general. Also, much better than the help docs on this topic.
