The correct option is Cinnabar.
Explanation
Mughal miniature paintings utilized natural pigments derived from minerals, plants, insects, and precious stones to achieve vibrant and durable colours. The preparation of these pigments involved elaborate processing to ensure longevity and brilliance.
Analysis of Pigments:
- Lapis Lazuli: A semi-precious stone imported primarily from Badakhshan, used to produce Ultramarine Blue.
- Orpiment: An arsenic sulfide mineral used to obtain a bright Yellow colour.
- Cinnabar: A mercury sulfide mineral (HgS). It was the primary source used to obtain Vermilion, a brilliant red or scarlet pigment often used for clothing and borders.
- Indigo: A plant-based pigment (Indigofera tinctoria) used to produce Dark Blue.
Key Takeaway: Cinnabar is the mineral source for the colour Vermilion (red) in Indian miniature paintings, while Lapis Lazuli provides blue and Orpiment provides yellow.
