In 1704 in Berlin, a color chemist named Johann Jacob Diesbach was experimenting with liquids that he had mixed using a familiar recipe. Instead of getting the expected carmine red, a deep blue color resulted. It was so beautiful that he decided to research its basis. He discovered that the inexpensive potash he was using was contaminated with blood traces, and the iron gave rise to the new pigment. Prussian blue conquered artists’ hearts immediately, as the paints made with it are exquisite.

"Their colors are just unbelievably beautiful, whether the sun is shining, or it's rainy weather, or night, with every play of light they look different again. Incredible."
