Pigment Blue 27 (C.I. 77510), commonly known as Prussian Blue or Milori Blue, is an inorganic pigment composed mainly of iron hexacyanoferrate. It is one of the earliest synthetic blue pigments and has been used in various coloring applications for more than three centuries.
Pigment Blue 27 produces a deep, intense blue shade, often described as dark blue with slightly greenish undertones. The pigment is formed through the reaction of iron salts with ferrocyanide compounds, resulting in a stable crystalline structure that provides characteristic color strength.
Due to its distinctive color and relatively good light stability, Pigment Blue 27 is used in coatings, inks, plastics, and some specialty industrial applications.
