In the past few years we’ve seen the debuts of the world’s blackest black (several times) and pinkest pink. Now comes a white acrylic paint, developed by engineers at Purdue, that reflects 99.5% of light and stays cooler than the ambient temperature even in the brightest sunshine. Meanwhile, artist Stuart Semple (who created that super-hot pink) has developed his own Whitest White, which (he says) reflects 99.6% of light. – Artnet
