Indigo, my favorite color, one of the seven colors of the rainbow.
The color was named after the indigo dye derived from the plant Indigofera tinctoria.
India is believed to be the oldest center of indigo dyeing. For centuries it was the only blue textile dye.
When trade routes opened in the 1500s, Europeans discovered tropical Indigo and over the next 300 years, it became a valuable commodity in world trade.
Nowadays, outside the industrial world, in traditional societies, indigo dyeing continues to be culturally and artistically important and
luckily in many places it still survives giving the world the most beautiful creations.
