The art of painting portraits, landscapes, animals, draperies, satins, &c. in oil colours : practically explained by coloured palettes : with an appendix on cleaning and restoring ancient paintings on panel or canvas
A practical oil-painting manual by John Cawse, published in London by Rudolph Ackermann in 1840 for amateur and student painters, teaching portraits, landscapes, animals and drapery through numbered colour palettes. The plates show wooden kidney-shaped palettes with grained wash and thumbholes, each carrying rows of numbered pigment blobs in white, ochre, crimson, blue, brown and black, giving designers ready-made colour charts, keyed swatch layouts and a recognisable artist's-palette silhouette.
