Functions:
1. Colorant - Pigments or dyes that are added in order to change or enhance the color.
Prussian blue is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. Another name for the color is Berlin blue or, in painting, Parisian or Paris blue. It is insoluble, but the crystallites tend to form a colloid. [1]
Because it is easily made, cheap, nontoxic, and intensely colored, Prussian blue has attracted many applications. It was adopted as a pigment very soon after its invention and was almost immediately widely used in oil, watercolor, and dyeing. In addition, Prussian blue's ability to incorporate monocations makes it useful as a sequestering agent for certain heavy metal poisons.
