 Bananas! A bunch of you asked me to paint them in my testing tube of Daniel Smith-Yinmin Blue. This is a lightfast, opaque pigment discovered by chemist Mas Suburmanian at Oregon State University while he was heating manganese oxide in a furnace and was quite surprised by the unexpected results. This color came to its name by its chemical symbols Y for yttrium, I-N for indium, and M-N for manganese. The color is sometimes called Oregon blue or mass blue at the university. Yinmin was discovered in 2009, it had been 200 years since the last blue pigment had been discovered and that was cobalt blue way back in 1802.
