The colour Blue makes history, again.
Yttrium, Indium, Manganese (Oxide), heated to 2,000F and mixed w/ chemicals resulted in an unintended vivid blue pigment called 'YInMn'.
Scientists at Oregon State University discovered YInMn in experiments "related to electronics" in 2009. It has now been licensed for commercial use.
Blue pigment has been a precious commodity for millennia. This one, 'YInMn' doesn't fade in oil or water and "reflects a large amount of infrared light" making it a possible product to develop for energy efficiency uses.
