What effect does the use of shiny green particles of beetle wings in Basohli painting aim to simulate?

Emeralds

Answer: Emeralds
The use of small, shiny green particles of beetle wings in Basohli painting aims to delineate jewelry and simulate the effect of emeralds.

The first and most dramatic example of work from the hill states is from Basohli. From 1678 to 1695, Kirpal Pal, an enlightened prince, ruled the state. Under him, Basohli developed a distinctive and magnificent style. It is characterised by a strong use of primary colours and warm yellows — filling the background and horizon, stylised treatment of vegetation and raised white paint for imitating the representation of pearls in ornaments. However, the most significant characteristic of Basohli painting is the use of small, shiny green particles of beetle wings to delineate jewellery and simulate the effect of emeralds. In their vibrant palette and elegance, they share the aesthetics of the Chaurpanchashika group of paintings of Western India.
