In 2009, a graduate student working in a chemistry lab at Oregon State University accidentally created a new, brilliantly blue pigment while experimenting with manganese oxide and other materials. Dubbed “YInMn blue” after its chemical makeup, the pigment quickly spurred a research paper and a patent application. And soon the gorgeous new color will be available to all of us: Crayola recently announced that it would introduce a blue crayon “inspired” by YInMn and kicked off a contest to name it.
