Heinrich Diesbach, the German painter and colormaker, was after Cochineal Red Lake, a pigment originally obtained by crushing the bodies of cochineal insects. Toward this end, sometime in 1704, in the laboratory of alchemist Johann Konrad Dippel, Diesbach mixed iron sulphate and carbonate of potash. The potash was contaminated with animal oil, however, and the result was not Cochineal Red. The potash (an alkali) reacted with the animal oil (prepared from blood), to create potassium ferrocyanide. Mixing this with the iron sulphate, created the chemical compound iron ferrocyanide, better known as the first modern synthetic pigment ever created, albeit accidentally: Prussian Blue.

Sweet color.  Somehow I thought you’d tie-in the American white nationalist teen folk duo...  “the horror, the horror.”

Yeah, I was doing my best to just ignore that whole angle, but “the horror” is just plain unavoidable isn’t it?
