Everything about this seems amazing to me. Harvard has a library comprised solely of the rarest of the rare colors and pigments.
The history of pigments goes back to prehistoric times, but much of what we know about how they relate to the art world comes from Edward Forbes, a historian and director of the Fogg Art Museum at Harvard University from 1909 to 1944. Considered the father of art conservation in the United States, Forbes traveled around the world amassing pigments in order to authenticate classical Italian paintings. Over the years, the Forbes Pigment Collection—as his collection came to be known—grew to more than 2,500 different specimens, each with its own layered backstory on its origin, production, and use.
