Sometimes gruesome, dangerous, or ridiculous, pigments have a colorful history.

The story was taken up by her nephew, Rudyard Kipling. “He descended in broad daylight with a tube of ‘Mummy Brown’ in his hand, saying that he had discovered it was made of dead Pharaohs and we must bury it accordingly. So we all went out and helped – according to the rites of Mizraim and Memphis, I hope – and to this day I could drive a spade within a foot of where that tube lies.”

Mummy Brown is not to be confused with Caput Mortuum, although the names were sometimes interchanged. Caput Mortuum was a purple form of hematite iron oxide, popular for painting the robes of saints. It was the by-product of sulfuric acid manufacture.
The pigment called Dragon’s Blood was supposedly a mix of dragon and elephant blood. “[Elephants] have continual warre against Dragons, which desire their blood, because it is very cold: and therefore the Dragon lying awaite as the Elephant passeth by, windeth his taile, being of exceeding length, about the hinder legs of the Elephant, and when the Elephant waxeth faint, he falleth down on the serpent, being now full of blood, and with the poise of his body breaketh him: so that his owne blood with the blood of the Elephant runneth out of him mingled together, which being colde, is congealed into that substance which the Apothecaries call Sanguis Draconis, that is Dragons blood, otherwise called Cinnabaris.” (Alchemist Richard Eden)
The Burning of the Houses of Lords and Commons, 1834-35, JMW Turner, courtesy Philadelphia Museum of Art. Turner used Indian Yellow extensively.
Dragon’s Blood actually comes from the sap of Dracaena cinnabari and is extremely fugitive. Not that true cinnabar was anything to write home about, since it contains toxic levels of mercury. Despite that, it was once a popular cosmetic and art material.
Indian Yellow was said to be made by feeding mango leaves to malnourished cows and collecting their urine. Historian Victoria Finlay searched legal records, visited the town where the stuff was allegedly made, and interviewed elderly locals. She concluded that the story was probably a fable to gin up interest in the color.
All of this leads to the pigment Kidney Hematite. By now, you’re wincing. But Kidney Hematite is just an ore with a distinctive shape. Ground or sculpted, it’s perfectly benign.
