This is awesome. I like how the color picker is set up in corel painter, and hate using the one in photoshop. Well, now you can have that color picker in photoshop! HOORAY! I'm using it for CS4 though, so I dont know if it works for any of the other CS's.
Anywho, thought I'd share.. you can get the picker for free at.. http://nerdchallenge.com/lenwhite/
