Cobalt blue is a shade of blue which was discovered in 1802 by a French chemist named Louis Jacques Thenard. Since then, the last shade of blue was accidentally discovered in 2009 when Mas Subramanian was working as a chemistry professor at Oregon State University. One of his students mixed yttrium, indium and manganese oxides before putting this mixture of chemicals in a furnace. When this mixture of chemicals were taken out of the furnace, it was a bright blue.
The compound is named YInMn and it is a very stable compound produced at high temperatures. YInMn is currently having the toxicity levels in order to be FDA approved. Crayola is also putting plans into place to turn this new shade into a crayon, but are asking for help to name the new crayon.
