Title: Demachy and red chalk
Try Venetian red, Indian red, or red ochre.
It was a red iron oxide pigment if I remember correctly. One recipe calls for 3
g. Venetian red powder to 1/2 oz. gum. Another calls for a pigment called "light
red" which I know was available about 10 yr ago anyway. But Venetian Red
is a nice brick-y color that you'd be happy with. My notes say this: "For
instance, a Venetian red or red ochre color was used to approximate the
rust colored conte crayon portraits."

lists of proprietary watercolours, nor is it in Cornelissen’s catalogue of
