This is a specimen of copper from the mines of Bisbee Arizona. As I chose to take a liberal interpretation to "Two Colors, I am not expecting anything higher than a 5, but I think it is a pretty piece.

Looks like a dried splatter of formerly molten metal, presumably copper from the color and the title. Excelent abstract that fully meets the challenge and gives the eye lots to see.
Isn't nature wonderful. Not sure how you did the lighting but it looks as if the colours are a little dull even though there is some evidence of burn-out in places
