The correct option is 1, 2 and 3 only.
Explanation
Jamini Roy was a pioneering modern Indian artist who rejected Western academic realism to embrace the visual language of Bengal’s folk art, specifically the Kalighat Pat style. His artistic evolution involved a conscious shift toward indigenous materials and techniques to reflect the simplicity and ethos of rural artisans.
Statement 1 is Correct: Jamini Roy restricted his palette to a limited range of seven basic, earthy colours. These included Indian red, yellow ochre, cadmium green, vermillion, grey, blue, and white. He applied these colours using the tempera technique, which uses a water-soluble binder.
Statement 2 is Correct: In his pursuit of a purely indigenous idiom, Roy abandoned commercially manufactured European paints. He experimented with and used organic materials found in rural Bengal, such as tamarind seed glue as a binder, mercury powder for vermillion, and alluvial mud for greyish tones.
Statement 3 is Correct: A defining characteristic of Roy’s folk-style paintings is the use of bold, sweeping calligraphic lines. He used lamp black (soot) to create these prominent black outlines that defined the figures and forms in his compositions.
Statement 4 is Incorrect: Jamini Roy did not import canvas from Europe; rather, he rejected expensive and foreign materials like canvas and oil paints. He preferred painting on locally available and affordable surfaces such as cloth, woven mats, and wood coated with lime, aligning his practice with the materials used by traditional folk craftsmen.
Key Takeaway: Jamini Roy’s "folk-style" phase was characterized by a total rejection of Western materials (canvas, oils) in favor of indigenous resources like natural earth pigments, tempera, lamp black, and local surfaces like cloth or lime-coated wood.
