A new blue exterior house paint may save you energy


YlnMn Blue

Not particularly developed for artistic purposes, the characteristics of this newly “found” inorganic pigment (quoted as the first new blue in over two centuries), “Yin Min Blue”, will certainly have art applications. This is not the first of pigments in this category to find a niche use in the art world.    Yin Min Blue is actually the result of a “happy “ accident in the research for new materials that could be used in electronic applications. In the course of the research (by an Oregon State University College of Science team lead by chemistry professor Mas Subramanian), manganese oxide was mixed with other compounds (hence the classification YlnMn which stands for Yttrium (Y), Indium (In) and Manganese (Mn) elements) and heated at high temperatures to test for structure. It was noticed that one of their samples turned out a very vivid brilliant blue colour.

One of the most remarkable structural characteristics of this pigment is that absorbs red and green wavelengths of light and while at the same time only reflecting the blue wavelengths in the light spectrum. This new inorganic pigment has been described as an intense blue colour with high solar radiation (IR) reflecting properties.  As it has been observed the resulting vibrant blue appears to be very durable and its core compounds are said to be so stable that “the colour does not fade”.   So, considering these facts, the initial application and use intended for this pigment will be in a variety of commercial products, for example as paint coatings for buildings and roofs. The coat of paint would help to keep buildings cool by reflecting infrared light.
