The pigment was accidentally discovered a decade ago by Professor M.A. Subramanian in Oregon. Composed of yttrium, indium, and manganese, it yields a blue pigment that is chemically stable, fade-proof, opaque and non-toxic.
Because some of the ingredients are fairly rare, the patented pigment is still mostly inaccessible as an artist's color, but Gamblin has made a 164-tube limited run of the color for oil painters at a cost of $75 per tube.
Professor Subramanian has experimented with other variations of the basic recipe, substituting some less expensive ingredients, and the result has been some additional colors, which also look promising.
