Hex colour ref: 5d76cb
A colourful note: the colour indigo was named after the indigo dye derived from the Indigofera tinctoria plant. India is believed to be the oldest centre of indigo dyeing in the Old World: the association of India with indigo is reflected in the Greek word for the dye, which was indikon.
The first known use of indigo as a colour term in English was in 1289 and it became a crayola colour in 1999 – rather late for a rainbow colour!
