YInMn Blue (for yttrium, indium, manganese) 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.

Discovery and development
In 2008, Professor Mas Subramanian received a NSF grant to explore novel materials for electronics applications. Under this project, he was particularly interested in synthesizing multiferroics based on manganese oxides. He directed Andrew E. Smith (a graduate student then) to synthesize an oxide solid solution between YInO3 (a ferroelectric material) and YMnO3 (an antiferromagnetic material) at 1,093 °C (2,000 °F). The resulting compound was not an effective multiferroic; it was instead a vibrant blue material. Due to Prof. Subramanian's extensive experience at DuPont Co., he recognized the compound's potential use as a blue pigment and filed a patent disclosure covering the invention. After publishing their results, Shepherd Color Company contacted Prof. Subramanian for possible collaboration in commercialization efforts. The pigment is noteworthy for its vibrant, near-perfect blue color and unusually high NIR reflectance. The color can be adjusted by varying the In/Mn ratio, but the bluest pigment, YIn0.8Mn0.2O3, has a color comparable to standard cobalt blue CoAl2O4 pigments.
The new pigment is being commercialized by the Shepherd Color Company. The shade will also be used on AMD's new Radeon Pro WX and Pro SSG professional GPUs for the energy efficiency that stems from its near-infrared reflecting property. In June 2016, Australian company Derivan released the YIn Mn (known as Oregon Blue) as an experimental colour in their artist range (Matisse acrylics). This experimental product was made using the Shepherd licensed pigment.

Properties and preparation
YInMn Blue is chemically stable, does not fade, and is non-toxic. Moreover, infrared radiation is strongly reflected, which makes this pigment suitable for energy-saving cool coatings. It can be prepared by heating the oxides of the elements yttrium, indium, and manganese to a temperature of approximately 1,200 °C (2,200 °F).
Uses
The pigment is very durable, retaining its vibrant color in oil and water.
American art supplies company Crayola replaced its retired Dandelion color with a new color based on the pigment. It held a contest for more pronounceable name ideas, and announced the new color, "Bluetiful", on 14 September 2017. The new crayon color will be available starting late 2017. The color is inspired by the new blue.
