The first blue pigment to have been created in over 200 years will serve as the newest Crayola crayon. “YlnMn blue” was not developed within an arts context, but rather accidentally discovered in in an Oregon State University (OSU) chemistry lab in 2009. Graduate student Andrew Smith made the discovery alongside Mas Subramanian after combining manganese oxide, yttrium, and indium, elements which also serve as the inspiration for the pigment’s name.

YlnMn blue has a unique elemental structure which allows its manganese ions to absorb red and green wavelengths of light, only reflecting back a deep blue. This color is so durable that even when placed in oil or water it does not fade which makes it an attractive and versatile commercial product. The vibrant blue will take the place of Crayola’s yellow Dandelion crayon, which is being retired after a 27-year-run. (Source)
