A colourful book from 1692.

A beautiful book of colors from 1692. In over 700 pages of handwritten Dutch, the author, who identifies himself as A. Boogert, describes how to make watercolor paints. He explains how to mix the colors and how to change their tone by adding “one, two or three portions of water." To illustrate his point he fills each facing page with various shades of the color in question.
