A crayon inspired by a new pigment
In 2009, chemist Mas Subramanian and his graduate student Andrew E. Smith made a new blue pigment at Oregon State University. They called it YInMn Blue, after the yttrium, indium and manganese in it. You can read how it was found in the Wikipedia article on YInMn Blue.
In May 2017, Crayola said a new blue based on that pigment would take the slot of dandelion, a yellow it had just retired. The crayon does not contain any real YInMn. Crayola asked the public for easier names and picked Bluetiful on September 14, 2017. The crayon reached stores late that year.
Two codes on Wikipedia
Wikipedia's list of colors gives Bluetiful as #3C69E7, with Crayola as the source, and that is the code used here. The Crayola crayon table on Wikipedia shows the same RGB numbers (60, 105, 231) but prints #263A79 next to them. That is a much darker navy and does not match those numbers, so it looks like a typo.
For other crayon blues, see Crayola's plain blue. The real pigment is often compared with cobalt blue.
