The History and Cultural Significance of the Colour Indigo
The colour indigo has a rich history and cultural significance. In ancient times, the colour was used to dye fabrics and was associated with wealth and power.

The production of indigo dye is a practice that has a long history, especially in India, which was the main source of it during the Greco-Roman period. In the 17th century, indigo dye became a highly prized resource in Europe and was imported from India through the Silk Road.
Issac Newton identified indigo in the range of light that is visible to the human eye. It is placed somewhere between blue and violet and is one of the colors in a rainbow. There is some disagreement on its precise location, as it can look like it is blending into both blue and violet, or even absent from the spectrum altogether.
