Vidhyasagar worked exclusively with black pigment and its various shades, creating captivating abstract compositions. His black and white series mesmerizes viewers with contrasting shapes against a backdrop of deep white space, evoking a sense of harmonious realms to explore. Over time, his canvases grew larger and darker, his brushstrokes became freer and more spontaneous, and he incorporated vivid hues. He chooses to depict shapes that often resemble evolving natural forms, such as clouds, smoke, fog, or dunes that slowly transform and diffuse into space. Even today, Upadhyay continues to experiment and develop his artistic style to convey his boundless curiosity and passion. His art ultimately embodies a vision of simplicity.
