This week we are celebrating color. Inspired by the last remaining days of the long-running The Language of Color exhibition at the Harvard Museum of Natural History as well as ArtWeek Boston, we’re offering a series of stories in Index that revolve around color. We’ll touch on the history of collecting colors at the Harvard Art Museums, the story behind Harvard’s signature color, how Index uses the color spectrum, and more. And look out for boards on our Pinterest page that focus on different hues found in our collections.
