The correct option is White and red.
Explanation
Prehistoric rock paintings in India, particularly those found in rock shelters such as Bhimbetka (Madhya Pradesh), serve as a vital record of early human life. These artworks, predominantly from the Mesolithic period, were created using natural mineral pigments found in the local environment.
Analysis of Colour Usage:
- Dominant Colours: The most frequently used colour combination in these paintings is white and red.
- Red (Ochre/Geru): Obtained from haematite (iron oxide), this colour was widely used to depict hunters, warriors, and animals.
- White: Derived from limestone or calcinated kankar, white was used for outlining figures, geometric patterns, and ornamentation.
- Secondary Colours: Green and yellow were used occasionally. Specifically, green was often associated with depictions of dancers, while red was associated with hunters.
- Absence of Colours: Colours such as blue were notably absent in prehistoric Indian rock art, likely due to the unavailability of natural blue pigments during that era.
Key Takeaway: The palette of prehistoric Indian artists was restricted to naturally available minerals, resulting in the overwhelming dominance of Red (Haematite) and White (Limestone) across major sites like Bhimbetka.
