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)
