Before 2009, when a team of chemists at Oregon State University developed a colour now known as YInMn Blue (quite unexpectedly), it had been 200 years since the last inorganic blue pigment was created. Now, YInMn Blue is available to artists as a paint and for commercial use. The beauty of YInMn Blue is that it is not only able to be widely duplicated via Subramanian’s formula, but is also nontoxic, making it safer to use — and perhaps more eco-friendly too. Previous PigmentsThe Forbes Pigment Collection at the Harvard Art Museums houses more than 2,500 pigments; YInMn Blue has recently been added and was prominently featured in a small display case on the fourth floor. “You’ve got synthetic ultramarine, which came along in 1826, but that was synthesising an already known pigment.”There will be naysayers — those who say they can’t see much of a difference between ultramarine and YInMn Blue.
