It took a pair of enterprising researchers with a delicate touch to isolate the composition of the nine colors -- painstakingly concocted by unknown artists from such substances as precious metals and minerals, ground chalk, copper, plants and even insects.
Gregory Smith, an artifact conservation specialist at Buffalo State College in New York, and Robin Clark, a chemist with the University College of London, managed to collect tiny fragments of paint tucked in the inner margins of the King George III copy of the Gutenberg Bible at the British Library.
Using a process called Raman spectroscopy, the two sent a tiny laser beam into the paint bits and on a few selected pages of the Bible. By analyzing resultant characteristic light patterns, they identified the chemicals that enlivened decorative letters or intricate drawings of flora and fauna.

Interesting history. Thanks for posting this article.
Congratulations to these researchers.
A job well done.
