A New Blue

Professor Mas Subramanian is a professor of materials science at Oregon State University, researching new materials that could be used in electronics. In 2009, one of his grad students, Andrew E. Smith took a mixture out of the furnace that had been heated to more than 2,000 Fahrenheit and found it had turned a brilliant, clear blue color. They had accidentally, serendipitously discovered a new blue pigment; the first new blue in more than 200 years. The last “new inorganic blue” to be manufactured was Cobalt Blue in the early 1800’s. Cobalt, however, was not lightfast and was toxic to boot.

Considered a “complex inorganic pigment,” the new blue is currently called YInMn blue, named for its chemical makeup of yttrium, indium and manganese oxides.

Subramanian, Smith and Oregon State University chemistry professor Arthur Sleight patented the YInMn material; Shepherd Color, an industrial pigment distributor is testing out the pigment’s application. Once the Environmental Protection Agency approves the color for commercial manufacturing, Shepherd is licensed to sell the pigment. So far, YInMn has proven to reflect heat more than Cobalt Blue and has proven to be remarkably stable; holding up against oil, water and sunlight better than other available blues. In addition to being light safe, none of the ingredients are toxic.

Once large manufacturers are using a pigment, the material trickles down to our art supplies. Keep your eyes open in the next few years for a brand new blue, which will most likely receive a sexier name for marketing purposes. And the team of “new blue” researchers are already working to create new colors by altering the mixture. They have created a purple by adding titanium and zinc and are expecting additional bright, vivid colors to follow.

National Public Radio (NPR) has an article online with interesting links about the new blue from July 16, 2016. Oregon State University has an in depth article about it as well.

Late Summer “Reads”: Links to Books and Online Articles and Podcasts about Color

Now that we’re hitting the dog days of summer, here are some interesting books, links and podcasts about color:

NPR has a series of free podcasts about color, called Color Decoded: Stories that Span the Spectrum. Read the articles, or listen or download them all from the link, or individually from any of the links below. Many of the following (in reverse order) are only a few minutes long, so queue them all up. Some of them have been featured on our BAGSC News blog previously. They’re fun listening while painting or drawing:

Each of the individual articles have links to other resources and stories about color: TED Talks, podcasts and news articles. It’s easy to journey deep into online color discoveries.

For those who prefer spending the end of summer curled up with a good book, here are a very few great reads about colors:

Not too long after Jim Folsom, published his free ebook, “A Botanical Reader for the Curious Gardener,” in February 2016, it mysteriously disappeared from iBooks, much to the disappointment of those who hadn’t yet had a chance to download it. The problem turned out to be some technical glitches.

Jim used the opportunity to issue version 1.2 of “A Botanical Reader” as they got the ebook back online. The new version includes edits, expansion of the Botanical Calendar, and an enlarged Plant Trivia TimeLine.

BAGSC News covered the initial launch of “A Botanical Reader” [read the full article at:]

The ebook is downloadable for free through iTunes/iBooks, at  It’s listed in the category of Life Sciences, and is available on the iPad, iPhone and Mac. Search in iBooks under “A Botanical Reader” or “James P. Folsom” and it will come right up. The print length is 332 pages. 

About the Author
James P. (Jim) Folsom, PhD., rides the demographic peak of baby boomers, having been born in southeastern Alabama in 1950. His lifelong love of plants is reflected in a BS in Botany from Auburn University, an MA in Biology from Vanderbilt University, and a PhD in research botany from The University of Texas at Austin. Though his research has centered on the orchid family, with much of the research time spent in Tropical America (including a year in Colombia on a Fulbright Pre-Doctoral Fellowship), Jim’s botanical interests are wide-ranging. As Curator of the Botanical Gardens at The Huntington in San Marino, CA, he dedicates much of his effort to educational programs that increase public interest and understanding of the science, culture, and history of plants and gardens. He lives at The Huntington with his wife, Debra (also a botanist) and children Molly and Jimmy. Jim was recognized as a Friend of the Cactus and Succulent Society of America in 1996, a Member-at-Large of the Garden Club of America in 1998, and presented a Professional Citation by the American Association of Botanical Gardens and Arboreta in 1999. The Garden Club of America awarded him their Medal of Honor in 2007.
