[PAR] [TLE] Prussian blue [SEP] Prussian blue is a dark blue pigment with the idealized chemical formula Fe7(CN)18 .  To better understand the binding situation in this complex compound the formula can also be written as Fe4[Fe(CN)6]3 · "x"H2O .  Another name for the color is Berlin blue or, in painting, Parisian or Paris blue.  Turnbull's blue is the same substance, but is made from different reagents, and its slightly different color stems from different impurities. [PAR] [TLE] Johann Jacob Diesbach [SEP] Johann Jacob Diesbach (] ) was a Swiss pigment and dye producer known for first synthesizing a blue pigment known as Prussian blue (i.e. iron blue or Berlin blue).
