Carmine (ˈkɑrmən,_ˈkɑrmaɪn) also called cochineal (when it is extracted from the cochineal insect), cochineal extract, crimson lake, or carmine lake is a pigment of a bright-red color obtained from the aluminium complex derived from carminic acid. Specific code names for the pigment include natural red 4, C.I. 75470, or E120. Carmine is also a general term for a particularly deep-red color. The English word "carmine" is derived from the French word carmin (12th century), from Medieval Latin carminium, from Persian قرمز qirmiz ("crimson"), which itself derives from Middle Persian carmir ("red, crimson"). The Persian term carmir is likely cognate with Sanskrit krimiga ("insect-produced"), from krmi ("worm, insect"). The Persian word for "worm, insect" is kirm, and in Iran (Persia) the red colorant carmine was extracted from the bodies of dead female insects such as Kermes vermilio and cochineal. The form of the term may also have been influenced in Latin by minium ("red lead, cinnabar"), said to be of Iberian origin. The word "carmine" has been used as a color name as early as 1799. It is a popular food color, used in yogurt, candy, gelatin, meat, and beverages including fruit juices. Female Dactylopius coccus (cochineal) insects were used for their red coloring power as early as 700 BC. South American civilizations crushed the bugs present on cacti to extract the carmine they contain. Carmine pigment was extensively used by the Aztec civilization to dye textiles. It was imported later to Europe during the 16th century. Red is a color often associated with power and social status. Through the centuries, red has been worn by tribal chiefs, kings and queens, and military officers. Cochineal was a major source of income for the Spanish Crown. By weight, it was a far more valuable commodity than sugar, making it especially lucrative for overseas trade. As part of the triangular trade, its production and consumption were intertwined with slavery. In European markets, the Spanish Crown had a monopoly on cochineal until 1820 when the French learned to cultivate them.
