Thanks guys! The pigments are colors that I picked up over the years on my travels. The green came from eastern Oregon and is probably the same green pigment that the original arrow fragment was painted with. I was driving out in the middle of nowhere and passed by what looked like a deposit of flint up on the side of a roadcut. I turned around to investigate it. It turned out to be opalite, a very weak, brittle material. Unfortunately it was laced with cracks that made it unusable for knapping. But what I did find was small emerald green nuggets of pigment eroding out of the deposit of opalite. I don't know what it is, possibly a mineral with copper in it, but it is a really striking green color. The orange ochre is stuff I picked up in roadcuts as well. The black is simply crushed charcoal.
