In Hinduism
Shilpashastra (iconography)
Indigo is denoted by the Sanskrit term Nīla and represents one of the materials used to make Colours in the ancient Indian tradition of Painting (citra), according to the Viṣṇudharmottarapurāṇa, an ancient Sanskrit text which (being encyclopedic in nature) deals with a variety of cultural topics such as arts, architecture, music, grammar and astronomy. In the Viṣṇudharmottarapurāṇa, various materials are seen to be used to make colours. e.g., Indigo (nīla). Also, five colours are regarded as the primary ones, (viz., white, yellow, colour of vilomata, black, dark blue.). A painter can create hundreds or thousands of colours by amalgamating the primary colours.

Shilpashastra (शिल्पशास्त्र, śilpaśāstra) represents the ancient Indian science (shastra) of creative arts (shilpa) such as sculpture, iconography and painting. Closely related to Vastushastra (architecture), they often share the same literature.
