Don’t you just love comparing paint swatches, ‘having a spin’ at the Pantone color wheel, flipping through hundreds of books and magazines, … and then suddenly finding that perfect hue? If so, then you owe a big thank you to Edward Forbes. As the director of Harvard University’s Fogg Art Museum from 1909 to 1944, Forbes traveled the world to collect more than 2,500 pigments from ‘Mummy Brown’ – yes, he amassed actual mummy dust – to so-called ‘Dragon’s Blood’. Talk about color management, right? The Forbes collection includes seven of the rarest colors in the world …
