Red cabbage is one of many varieties of cabbage grown in temperate regions worldwide. Its juice contains the pigment cyanidin, which is used as a homemade indicator of acids and alkalies because it turns the purple colored juice pink when an acid is added and blue when mixed with an alkali (or colorless in a strong alkali solution).
