Prussian blue (also known as Berlin blue, Brandenburg blue, Parisian and Paris blue) is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. It has the chemical formula Fe 3+ 4 [Fe 2+ ( CN ) 6 ] 3 .
Prussian blue is a dark blue pigment containing iron and cyanide produced by the oxidation of ferrous ferrocyanide salts. It was invented in Berlin between 1704 and 1710. It was invented in Berlin between 1704 and 1710.
Johann Jacob Diesbach (German:) (born around 1670 – died in 1748), [1] was a German pigment and dye producer known for first synthesizing a blue pigment known as Prussian blue (i.e. iron blue or Berlin blue).

Engineer's blue is prepared by mixing Prussian blue with a non-drying oily material (for example, grease).The coloured oil is rubbed onto a reference surface, and the workpiece is then rubbed against the coloured reference; the transfer (by contact) of the pigment indicates the position of high spots on the workpiece or conversely highlight low points.

Prussian blue was first accidentally made around 1706, by heating substances containing iron and carbon and nitrogen, and other cyanides made subsequently (and named after it). Among its many uses, Prussian blue gives the blue color to blueprints, bluing, and cyanotypes.
