    Indigo is a color named after the blue dye derived from the plant Indigofera tinctoria and related species. The color is placed on the electromagnetic spectrum between about 420 and 450 nm in wavelength, placing it between blue and violet.

    To our eyes it looks dark blue but it is actually a little darker than blue.
