How is indigo naturally made?

Indigo is naturally made from a variety of plants in the Indigofera family, including Indigofera tinctoria, true indigo and wild indigo.

The dye can be extracted from the leaves, bark or wood of these plants by crushing them and steeping them in warm water.

This process creates a yellow-green liquid that oxidizes to form insoluble blue particles when exposed to air.

These particles are filtered off and combined with an alkali such as lye or ammonia to create a dark blue liquid known as “indigo paste”.

This paste can then be dried into flakes or powder for use in dyeing fabrics.

In some cases, natural indigo may need further processing before it is ready for use.

For example, extracting it from certain species requires heating the material at high temperatures before adding an alkali to achieve the desired color results.


No matter where it’s used, indigo will always be associated with its rich history and symbolism throughout the world.

Whether you are looking for a vibrant shade to express your creativity or a deeper hue to evoke calmness and inner peace, you can find just what you’re looking for in the world of indigo!
