It was also known as “Alexandria blue” – For Egyptians it was the color of heavens, associated with Nile, and the luminescence of blue was due to Lapis Lazuli, which made it expensive!
Prussian Blue was the first modern synthetic pigment – also called as “engineer’s blue”, and used in blue prints, laundry bluing and of course it was the uniform of Prussian army too. It was first synthesized by Diesbach, a German dye producer.
