Carmine (/ˈkɑrmɪn/ or /ˈkɑrmaɪn/), also called crimson lake, cochineal, natural red 4, C.I. 75470, or E120, is a pigment of a bright-red color obtained from the aluminium salt of carminic acid; it is also a general term for a particularly deep-red color of the same name. The pigment is produced from some scale insects such as the cochineal scale and certain Porphyrophora species (Armenian cochineal and Polish cochineal).
