The Klaer Lightende Spiegel der Verfkonst (literally: "clearly lighting mirror of the painting art") is a manuscript with over 700 pages [1] of color swatches, produced in 1692 [2] by a Dutch author from Delft known only as A. Boogert. [3] The book is arranged according to the Aristotelian system rather than the spectrum, which had recently been described by Newton. [1] Only one copy of the manual is known, and it is completely handwritten and hand-painted. [4] It is kept in the Bibliothèque Méjanes in Aix-en-Provence. [5]
