What colour is Pala indigo?

Pala indigo is a small to medium tree with smooth yellow-brown bark and white flowers that turn cream as they age. It grows in dry and moist areas across India, Southeast Asia, and Australia. The tree is known for its pale, ivory-like wood and for leaves that can be processed to make a blue dye similar to indigo.

Where does Pala indigo come from?

The name 'Pala indigo' comes from its use as a source of blue dye, much like the better-known indigo plant. Wrightia tinctoria has been described in botanical records since the early 1800s, with British botanists noting its presence in southern India. Its wood has been compared to ivory for its whiteness.

How is Pala indigo made?

The blue dye is obtained from the leaves of the tree. To produce a single kilogram of dye, a large quantity of leaves is required. The leaves, flowers, fruits, and roots all contain a compound that yields the blue colour. The process involves extracting and processing the plant material to release the dye.

Where Pala indigo is used

The dye from Pala indigo is used in textiles and sometimes in body art. Its pale wood is highly valued for carving, especially in the making of toys and small boxes in places like Channapatna, India. The plant is also grown for fodder, green manure, and as an ornamental tree in tropical gardens.
