B. Prabha drew her inspiration from Amrita Shergil. She was moved by the lives of rural women, and over time, they became the central theme of her work.
She worked mainly in oil, in an instantly recognizable style. She is best known for graceful elongated figures of pensive rural women, each canvas in a single dominant colour.
Her work has been included in exhibitions such as 'Winter Moderns" at Aicon Gallery, New York, in 2008. Over the years, she held more than 50 exhibitions in India and abroad and is featured in some important collections, including India's National Gallery of Modern Art.
