100’s Of Shades Of Blue And One New Shade Of Blue Is Set To Change Our Homes For The Better

Color is an integral part of our lives. We see colors everywhere. No matter where we are. Inside, outside, up, down, and all around. The sky is blue. The grass is green. The clouds in the sky are white. In the realm of colors, there are hundreds of shades, tints, tones and other variations. And that applies to each one of them. Look around and notice how many you see.

Scientists are busy trying to discover more. It’s a tedious  process. It can involve a lot of trial and error. So when a university professor discovers one by accident, it’s unusual. And that is exactly what happened at Oregon State University. A chemist was looking for materials that contained magnetic properties.

Read the rest of the story here:

This pigment is nontoxic and so bold and durable that it won’t ever fade.

The color you see below is no ordinary hue.

It’s one of the world’s newest — and perhaps most vivid — shades of blue. It also happens to be the result of a brilliant mistake.

A team of chemists discovered YInMn blue during a chemistry experiment at Oregon State University in 2009. “It was serendipity, actually,“ said Mas Subramanian, the OSU chemist who led the experiment, in a press release. “A happy, accidental discovery.”

Now scientists have perfected the pigment and it’s going on sale as an option in commercial coatings, plastics and household paint this year.

It all started when Subramanian and his team were trying to find materials with magnetic properties that could be used in computer hard drives. The OSU chemists mixed manganese oxide, which is black in color, with a variety of chemicals. They then heated the mixture to nearly 2,000 degrees Fahrenheit.

After a failed test run, one of Subramanian’s graduate students removed the mixture from the furnace, only to find an impossibly blue powder.

“I expected [the resulting substance] to be brown or black,” Subramanian said in 2014. “But when I saw what he had, I knew this was something unusual.”

The chemists named the vibrantly pigmented powder YInMn blue after the chemical elements of which it is made: yttrium, indium and manganese, according to artnet News. They published their findings on the colorful discovery last year in the Journal of the American Chemical Society.

The pigment’s intense blue hue is a result of its unusual crystal structure, known to chemists as trigonal bipyramidal coordination. This structure allows the pigment’s manganese ions to absorb all red and green wavelengths of light, while reflecting back only blue wavelengths, according to an OSU press release.

And the spectacular color isn’t just a sight to behold.

The YInMn blue pigment also possesses unique characteristics which make it a coveted material for commercial companies and artists alike.

Art restorers, in particular, are interested in YInMn blue because the compounds that make up the vibrant pigment are so stable and durable, the color won’t fade, artnet News reported. What’s more, the pigment can be “tuned” to produce a wide range of blues, from sky blue to near black.

The pigment could also be used in roofing materials. Since YInMn blue reflects about 40 percent of infrared energy, it could keep buildings cooler. So it could reduce air conditioning costs.

A hallmark of the pigment is that it contains zero toxic ingredients, Subramanian says. That makes it a safer alternative to existing blue pigments, such as Prussian blue, which have toxic properties.

“Ever since the early Egyptians developed some of the first blue pigments, the pigment industry has been struggling to address problems with safety, toxicity and durability,” Subramanian said in a press release.

Since details of the pigment’s discovery were published last year, Subramanian has worked with paint manufacturers, conservation companies and chemical firms which make pigments for plastics, inks, cosmetics and coatings for cars and aircrafts.

And while practical applications for the pigment could make our world a greener place, our favorite uses of YInMn blue are accomplished with a paintbrush.

Subramanian has given samples of the pigment to several artists, allowing them to experiment creatively with the vibrant hue.

“It is a rare ‘Art Meet Science’ moment,” Subramanian said of the creative collaboration.

The diverse use of this new color blue is a milestone in pigment and color discoveries. Because the makeup of this new pigment is so stable and durable, it won’t fade. It can also be tweaked to make many different shades of blue. It also has practicle applications in the manufacturing of homes. If you put it on the roof, the house will stay cooler and lower the cost of air conditioning. This new discovery has been a long time coming. It will expand the research in this area and will broaden the use of future new pigments and colors.
