Also known as Milori Blue or Berlin Blue.

Around 1704, the paint maker Johann Jacob Diesbach from Berlin discovered how to produce a beautiful blue color from iron salts and cattle blood waste. Since then, this pigment has been marketed under a wide variety of names, such as Paris blue, Milori blue, Prussian blue or Berlin blue. The Pigment Blue 27 pigment is suitable for all applications in pH-neutral binders. It cannot be processed in acids or alkalis or at higher temperatures.
