Scientists have discovered a new shade of blue that could be perfect for roofing products. YlnMn Blue, discovered in 2009, is "unusually good at reflecting infrared light, which could make it useful in roofing materials, reflecting sunlight to keep buildings cool," Shaunacey Ferro, staff writer at, writes. The color was discovered by Mas Subramanian, a professor at Oregon State University, when he was running experiments to produce new technologies for electronics. During the experiments, he and his team developed something else: YlnMn Blue. The new shade is made by "heating a mixture of black manganese oxide and other chemicals to almost 2000°F" and is made from non-toxic ingredients, Ferro writes. Now, seven years after discovery, YlnMn Blue will be available to manufacturers and artists to use in their products.
