these colors no longer exist. technically.
i wish the small text was legible ):
here, have a transcription!
(1) Ivory Black
This deep blue-black was made from the burned and charred waste of ivory. It fell out of use as ivory did.
(2) Caput Mortuum
A tarry brown pigment made up of ground-up Egyptian mummies, “caput mortuum” means “worthless remains.” (I cringed transcribing this.)
The color of mercuric sulfide cinnabar, vermillion was beautiful but rare, unstable, and toxic.
(4) Red Dye #3
The US Government banned this red food and cosmetics dye in 1990 for being carcinogenic.
Realgar is a highly toxic arsenic sulfide that was once the only pure orange pigment available.
(6) Indian Yellow
Supposedly made from the urine of cows only fed mango leaves, this color would have become rare due to its poor effects on cattle.
(7) Lead White
White paint that got its color from lead was a great pigment, but deadly.
A moderately transparent bluish green with low stability, verdigris is a copper acetate, and quite toxic.
(9) Chartres Blue
This blue, used to color stained glass in France’s Chartres Cathedral, proved incredibly difficult to make.
Made from ground-up glass and cobalt, this blue was complicated to manufacture and faded easily.
