  1. Indigo

    Indigo is a color that is traditionally regarded as a color on the spectrum between 450 and 420 nanometers and as one of the seven colors of the rainbow--the color between blue and violet. Although traditionally considered one of seven spectral colors, its position in the electromagnetic spectrum is controversial according to some recent research. Some people regard indigo as a deep and bright variation of blue close to the color wheel blue, as well as to some variants of ultramarine. The color indigo was named after the Indigo dye derived from the plant Indigofera tinctoria and related species. The first recorded use of indigo as a color name in English was in 1289.

Chambers 20th Century Dictionary
