The Story Behind Indigo
Indigo was one of history's most valuable dyes, extracted from plants in the genus Indigofera and traded across continents for centuries; it's also the dye that gives blue jeans their color. Isaac Newton included it as a distinct band in his description of the rainbow, though many people today struggle to tell it apart from blue or violet.
