I'm sorry to post this but I found it very interesting. I'm sitting drinking a cup of coffee here and I have added to it some cocoa that I bought yesterday. I never saw the stuff before. It is called black cocoa. When I got to the bottom of the cup, there was this thick pastey cocoa goop on the bottom. It has an oily kind of consistency and I recall Eva (I forget her screen name, but she was from Germany) saying that she used coffee, cigarette ashed and other things in her water colors. This black cocoa makes the most vibrant, lifelike dark chocalate brown color that I have ever seen. Vibrant? Anyway...Is it possible to use this powder in painting somehow to achieve the color?
