It's one of those random things that I'm not really sure where it came from, but that's part of the beauty of the interwebs. Maybe it was from Booooooooom, I'm not sure, but I've recently come across the artist David Slone.
He uses some color in some interesting ways so I thought I would pass it along to you. Search around his site and I think you'll find some color and paint use within his portraits that you find kind of cool. Well, maybe. Check it out.
