YInMn Blue (named because it contains Yttrium, Indium, and Manganese) is the first new inorganic blue pigment in over 200 years, and the first genuine single-pigment alternative to Cobalt Blue. Discovered accidentally by materials scientists at Oregon State University, YInMn Blue is a deep, stable, opaque blue that will surely become an important artist's pigment in the years to come.

Why is YInMn Blue so special? It exists in color space between ultramarine (warm blue) and phthalo blue (cool blue). The only similar pigment is cobalt blue, but YInMn Blue is more opaque, less toxic, and much more brilliant. We think it's the ultimate primary blue, and the comparison with multi-pigment primaries mixed from ultramarine and phthalo couldn't be more stark. While mixed primary blues are often muddy and unimpressive, YInMn Blue provides a single-pigment primary that is incredibly clear.

This remarkable new discovery has only just begun to be commercially manufactured. YInMn Blue exists only in small quantities, and YInMn Blue paints have been made only in limited editions by various color houses. Earlier this year, we offered a limited-run YInMn acrylic from Schmincke, the legendary German manufacturer, and ever since, we've been receiving inquiries from watercolorists wondering when they'll get to try it.

As it turns out, Schmincke had the same thing in mind, and their latest limited edition is a professional-grade watercolor made with this rare pigment. Like the rest of their Horadam lineup, this YInMn Blue watercolor is smooth, easily mixable and brushable, and highly pigmented. YinMn Blue is extremely lightfast, so this color carries Schmincke's highest rating for permanence.

Packaged in a 5 mL metal tube. Made in Germany. Available while supplies last.
