YInMn Blue

YInMn Blue (for yttrium, indium, manganese), also known as Oregon Blue and Yin Min Blue, is an inorganic blue pigment that was accidentally discovered by Professor Mas Subramanian and his then-graduate student Andrew E. Smith at Oregon State University in 2009. [2][1] The color can be adjusted by varying the In/Mn ratio in the pigment’s base formula of YIn
