These colour charts come from the oldest known book on colour – long before Pantone! – since its author is a Dutchman of the XVII century, A. Boogert.

The full title of the original book is very long but can be summed up as "Traité des Couleurs servir à la peinture à l'eau" - Treated Colors used for water-based painting. It is kept at the Méjanes Library in Aix-en-Provence.
