A 1912 book called Color Standards and Color Nomenclature contains 1,115 hand-painted color swatches, each one mixed and applied by the ornithologist Robert Ridgway and his wife Julia. The book was the direct ancestor of the Pantone color system. Fifty years later, when Lawrence Herbert bought a printing company and created Pantone, he referenced older color guides — including Ridgway's — to build his standardized system. Ridgway had started the project decades earlier because he was frustrated that fellow bird scientists could not agree on what "brownish-blue" meant. That is the throughline of one of the three main stories in this episode: the hidden natural history of something we treat as a commercial abstraction.

Show Notes

Alexis Nikole joins the show to talk about the heinous etymology of the juneberry (if that's even it's real name...). Plus, Liz Clayton Fuller returns to explain how birds are behind Pantone, and Rachel details the ins and outs of Naked Mole Rat society -- and what it has to do with their STINK.
