Sita Ray nurtured her passion for painting during the resurgent period of modern Art in India as it was merging with global trend. She graduated in 1959 from the eminent Delhi School of Fine Arts. The then eminent painters of the school motivated and empowered her to join this movement from the very beginning.

After graduation she pursued her artistic profession with zeal and enthusiasm for many years and painted in various styles, on diverse subjects and through different media like Oil, Water Color and Pastel. Her artistic inspiration came from the cultural exposures she had almost for four decades as she traveled widely across India, Europe, the USA, the UK, North Africa , Korea, China , Australia, New Zealand, and other parts of South East Asia.

It so happened that most of her professional life she lived was in Japan. Its artistic ambience all around, beautiful landscapes with seasonal variations and subtlety of aesthetic culture made deep impression on her work. No doubt it was the most creative period in her career. Along with western and oriental techniques she pursued vigorously Japanese art styles of Sumi-E and Nihon-Ga under the guidance of traditional masters. Her artistic techniques and styles of this later period evolved distinctly from the blending of Indian and Japanese feelings and sensibilities.

During her academic career Sita Ray specialized in portrait paintings. Consequently many of her compositions in oil were based on the application of human figures from various angles to depict the theme of her painting. Besides experimenting with the conventional media in her earlier work she developed the special technique of using oil with transparency like water color that enhanced the brightness and vibrancy of the color of her canvases.
Sita Ray's untimely death had deprived us of a singular artist , rare in our time , one who had such a child like vision of the world we live in.

Some of the major themes of her paintings were: Rhythm in Indian life, Color Green , Enlightened One ( Life of Buddha),

She held a number of solo-exhibitions in India and Japan at well known galleries and her work was highly acclaimed by the art lovers and critics.

Presently exhibition of her paintings is being planned in Tokyo in Oct end and mid Nov. sponsored by Indian Embassy in their newly constructed Art Gallery. Some of her best paintings selected from diverse subjects and different media are expected to be put up in this exhibition.
