Mas Subramanian, a chemist by trade, found himself unexpectedly drawn into the world of art and color when he stumbled upon an exotic blue pigment in his laboratory in 2008. This chance discovery marked the beginning of a journey that would lead him to explore the intricate connection between chemistry and color in a quest to create the perfect red pigment.
Historically, obtaining vibrant and durable red pigments has been a challenge. Early artists used iron oxide-containing rocks to create red paints, resulting in robust but muted colors. Toxic metals like cadmium and mercury were later used to achieve vivid reds, but environmental concerns have led to the search for safer alternatives.
Subramanian’s exploration of color began with the discovery of YInMn blue, a striking blue pigment made from yttrium, indium, and manganese. This accidental find sparked his interest in pigment chemistry, inspiring him to experiment with different elements to create a range of colors.
While blue proved to be a relatively easy color to achieve, red presented a more complex challenge. The key to creating vibrant red pigments lies in the atomic structure of the material, which determines how light interacts with electrons to produce specific colors. Subramanian’s innovative approach involves introducing asymmetry into the crystal structures of compounds containing chromium in the rare Cr2+ state, mimicking the conditions found on the moon to stabilize the element.
Despite his meticulous experimentation and theoretical insights, Subramanian acknowledges that creating the perfect red pigment remains a daunting task. The pigment must not only exhibit a vivid and long-lasting red hue but also withstand environmental factors and large-scale manufacturing processes.
As Subramanian continues his quest for the ideal red pigment, he remains committed to the process of experimentation and discovery. His unique approach to pigment chemistry has not only transformed his scientific endeavors but also deepened his appreciation for the artistry and beauty of colors. By bridging the gap between art and science, Subramanian has found a newfound passion for paintings and the hidden chemistry of color.
