During his nine-year sojourn into the strange, finicky realm of color, Subramanian, a materials science professor at Oregon State University at Corvallis, has grown infatuated with a form of chemistry that he, like many of his peers, once considered decidedly low-tech. His renown derives from his accidental creation, in 2009, of a new pigment, a substance capable of imparting color onto another material. YInMn blue (pronounced YIN-min) is an amalgam of yttrium, indium oxide, and manganese—elements deep within the periodic table that together form something unique. YInMn was the first blue pigment discovered in more than 200 years.
It isn’t only the exotic blueness that has excited the color industry, but also the other hues the pigment can generate. Subramanian soon realized that by adding copper, he could make a green. With iron, he got orange. Zinc and titanium, a muted purple.
