Pokraskin The term iron blue pigment as defined in ISO 2495 has largely replaced a great number of older names (e. g. Paris blue, Prussian blue, Berlin blue, Milori blue, Turnbull’s blue, toning blue, and nonbronze blue). These names usually stood for insoluble pigments based on microcrystalline Fe(II)Fe(III) cyano complexes; many were associated with specific hues. A standardized naming system has been demanded by users and welcomed by manufacturers, and has led to a reduction in the number of varieties [3.169].
Iron blue [14038-43-8], C. I. Pigment Blue 27:77510 (soluble blue is C. I. Pigment Blue 27:77520), was discovered in 1704 by Diesbach in Berlin by a precipitation reaction, and can be regarded as the oldest synthetic coordination compound. Milori was the first to produce it as a pigment on an industrial scale in the early nineteenth century [3.170].
