Prussian blue
Iron-based paint color
Prussian blue is a deep, intense blue pigment with a slightly greenish cast, discovered accidentally in early 18th-century Berlin.
It was the first modern synthetic pigment and revolutionized painting by offering an affordable alternative to ultramarine.
The color appears in works from Hokusai's woodblock prints to Picasso's Blue Period.
In medicine, Prussian blue treats heavy metal poisoning by binding radioactive cesium and thallium in the gut: Doctors administered Prussian blue after the radiation exposure.
