In the oddly-specific titled 1904 book, 739 Paint Questions Answered, the publishers of The Painters Magazine offered the following recipe for mixing foolproof caucasian flesh, with only one small caveat:
#15 Flesh color is usually made by mixing French ochre and English vermilion, but the principal requisites are that the painter has the necessary talent to paint faces. (page 9)
The book, which was geared more toward decorators and house painters than the fine artist, also offered advice on other topics, such as how to finish a bowling alley, re-paint a hearse white, climb a flagpole without spurs, and how to paint a locomotive (literally). Though the flesh mixture offered is interesting, the rest of the book seems to serve as more of a curiosity than of any technical help to the fine painter; almost all of the information is out-of-date to everyone but the historical home renovator.
