Color Theory book from 1692
271 years ago, an artist known as “A. Boogert” created this 800-page book of color formulas. From Colossal:
Spanning nearly 800 completely handwritten (and painted) pages, Traité des couleurs servant à la peinture à l’eau, was probably the most comprehensive guide to paint and color of its time. According to Medieval book historian Erik Kwakkel who translated part of the introduction, the color book was intended as an educational guide.
