The correct option is Lamp black.
Explanation
Pattachitra is a traditional cloth-based scroll painting art form originating from Odisha. It is characterized by intricate details, mythological themes, and the exclusive use of natural and mineral colours prepared by the artists (Chitrakars).
Analysis of Pigments:
- The preparation of colours in Pattachitra is a rigorous traditional process using organic sources.
- Black: The black pigment is traditionally obtained from Lamp black. This is soot collected by burning oil lamps or sometimes by burning coconut shells. The soot is then mixed with wood apple gum (Kaitha gum) to create a durable paint.
- White: Derived from powdered, boiled, and filtered conch shells.
- Red: Obtained from a mineral called Hingula (Cinnabar).
- Yellow: Obtained from a stone called Haritala (Orpiment).
- Blue: Traditionally derived from Ramaraja (Indigo).
Key Takeaway: Pattachitra paintings rely entirely on natural pigments, with the black colour specifically derived from lamp soot (Lamp black), distinguishing it from art forms that might use charcoal or synthetic dyes.
