Prussian blue is a deep blue pigment created by mixing iron salts with cyanide or by reacting iron(III) chloride with potassium ferrocyanide. It primarily consists of iron and cyanide ions, resulting in its distinctive intense blue color. The pigment itself does not require other colors to create it, as it is a specific compound rather than a mixture of other pigments.
