Awesome!

I tested it out, and it actually worked really well for my specific use
case.  I wanted to erase the color from a shadow, leaving just the shadow,
and it did that beautifully.

In the example with the lion, it works really well when you have a yellow
mane against a blue sky.  But completely wrong for a yellow body against
yellow wheat.

I updated the blog post with pictures if you're interested:
