Inside the Library That Holds the World’s Rarest Colors
Alongside a few tubes of Mummy Brown are other pigments whose origin stories are practically legend. Tyrian purple, an ancient Phoenician dye that requires 10,000 mollusks to produce a single gram of pigment, is said to have been discovered by Hercules’s dog as he snuffled along the beach. Indian yellow, purportedly made from the urine of cows fed only on mango leaves, was banned by the British government in the early 20th century on the grounds that its production constituted animal cruelty. Ultramarine, a vivid blue made from lapis lazuli mined in Afghanistan, was once more precious than gold.

Since that project concluded in 2007, there’s been a renewed interest in fortifying the Forbes Collection for the 21st century. Recent additions include plastic baggies of Day-Glo pigments often used by nun-cum-Pop artist Sister Corita Kent
in her prints; Vantablack, the world’s “blackest black,” which sparked controversy when it was licensed solely to sculptor Anish Kapoor; and artist Stuart Semple’s response, the world’s “pinkest pink” that can be purchased by anyone but Kapoor.
