As a kid, I figured that the spectrum of colors was pretty much fixed, defined by the different hues in the rainbow, and in the natural world, and in the Crayola 64 collection of crayons with the crayon sharpener built into the back of the box where the crayon your kid sister was trying to sharpen broke off and you could never use the sharpener again.
Then, as I grew older, I realized that new colors were being developed virtually every day, primarily for the purpose of requiring mystified husbands to go into paint stores and try to distinguish between tiny gradations shown on tiny paint sample squares, when their wives were trying to figure out which color to paint the dining room. I question, for example, whether “sea foam” was actually a color until some paint mixologist at Sherwin Williams or Benjamin Moore chuckled with evil glee and decided that tantalizing people with “sea foam” would make the home redecoration choices even more difficult.
But blue colors are different. Shades of blue tend to fade easily, and often contain toxic elements. That’s why it’s noteworthy that recently, for the first time in two centuries, a new blue pigment that is stable and doesn’t fade has become commercially available. It’s called YInMn, which is short for some of the chemical components of the color — Yttrium, Indium, and Manganese — and it was discovered accidentally by scientists at Oregon State University who were testing materials for use in electronics applications. They applied extreme heat to the compound, and the vivid, eye-popping blue shown above emerged. You can read about the discovery of the pigment and the chemistry behind it here.
The people are the paint stores are already smiling about it, and putting the YInMn paint squares out there in the sample case, right next to cobalt, lapis, and azure, ready to trap the next unwary husband asked to express an opinion about which one he prefers and then forced to explain why he likes that one better than the rest.
