Colour me indigo
Indigo, one of the oldest dyes, which changed the world in so many ways, has been a fascinating subject for us for a while. This page is dedicated to the mystery of Indigo which we will continue to explore. We will share our passion and evolving knowledge with like-minded people through our talks and textiles tours.
Indigo is considered to be the world’s oldest textile dye
There are early archaeological finds of indigo from over 6000 years ago in the Indus Valley on the Indian sub-continent, then 4000 years ago in Egypt, India and China. However researchers believed that the history of indigo stems back even further, as early as the Neolithic age. It is even believed that our ancestors used indigo in cave art and for painting their bodies. It is suggested that this is why we call it indigo, a greek word meaning “coming from India. Although blue occurs in many instances in the plant world, commonly in flowers and berries, most naturally occurring blue plants-stuffs are unsuitable for dying. Some can be used to derive some colour (for food or textiles) but the blue colour is not long-lasting. Indigo, on the other-hand, is the only natural source of long-lasting blue colour for textiles. However, indigo the colour does not occur in nature. The plants from which we derive indigo do not show any blue in their leaves, stems or flowers. Rather the colour indigo is achieved by fermenting the leaves of certain plant varieties to create indigo dye. Historically, indigo maintained it’s place since it was the only blue dye available and still today, after more than 150 years of organic chemistry and quite a few competitive dyes of blue colour, it is still the most efficient blue dye or pigment. in fact there is no other substance that creates such intensive blue colour with such few carbon atoms in its molecule.
Frequently Asked Questions
How are patterns created on the fabric?
Patterns are created using dye resist techniques:
- Tied (Bandhani)
- Wrapping, twisting, binding, folding, clamped, stitching (Shibori)
- Wax resist (Batik)
- Paste resist with starch (cassava or rice) or mud (Adire or Ajrak)
How does the colour get fixed?
Indigo is a vat dye, it does not require a fixer or mordant to adhere to fabrics.
To get deeper blue or almost black colour, the fabric has to be dipped in the vat multiple times. The dye deposits on the fabric layer by layer for the colour intensity.
Is there a revival in the use of Woad, source of blue dye in Europe, for dyeing textiles?
Yes, there have been many attempts to revive woad (Isatis tinctoria). How successful it depends on us as consumers. We at ATI, are here to rekindle these discussions and build awareness in the society.

Derived from the leaves of shrubs in the Indigofera family, indigo dye has been used for millennia in most regions of India to colour yarn and fabric (especially cotton) in shades of blue. Indigo is a substantive dye, fixing without the help of a mordant, but requires expertise to successfully prepare and use. The process was demonstrated for the V&A by the Cheepa family, indigo dyers living and working in Kala Dera, Rajasthan. www.vam.ac.uk/content/exhibitions/the-fabric-of-india/

Natural Indigo Dye for Denim in USA
Denim is dyed with natural indigo grown in Tennessee. An alternative to the synthetic dyes used for most jeans, it restores the soil, requires no chemical pest control and helps American family farmers keep their land in profitable production.
Adire in Nigeria
Adire is indigo resist-dyed cotton cloths that were made by women throughout Yorubaland in south-western Nigeria. Resist-dyeing involves creating a pattern by treating certain parts of the fabric in some way to prevent them absorbing dye.
