One such portrait is the portrait of Francisco Goya with his palette, painted in 1827, by Vicente López y Potańa (1772-1850) shown at right.
Goya used nine separate colors and arranged them on the palette with the white on nearest the thumbhole and the blacks on the opposite side.
Besides the white and blacks, there are only earth colors. We see the nine colors arranged along the outer edge of the palette as follows: Flake white, yellow ocher, brown ocher, light red, burnt Sienna, and four blacks. As on most 18th century palettes, vermilion is placed separately near white, as is described in de Piles' palette.[1]
It seems that Goya used no scaled palette or row of tints at the center of the palette. We observe a flesh tint, the blacks and a greenish and brownish tint that can be obtained by mixing the yellowish or reddish flesh tint with the black. An unusual feature of this palette is the great quantities of blacks (four) and the apparent absence of umbers. The abundant use of black for the groundwork of his paintings gives his pictures a definite character. There is no blue or green on Goya's palette.[2] Earth colors can be very brilliant and of high tinting strength: yellow ochre looks almost like Naples yellow, light red like vermilion, burnt Sienna like Crimson lake, and green earth (when used) like viridian.
F. Schmid identifies the different blacks as bone black, lamp black, ivory black and peach black. He admits this description of blacks, which in the painting have a warm or cold quality, is arbitrary and guess-work based on comparison with contemporary treatises where the blacks are described in words. For example, de Piles (1684) recommends two blacks in the row of the pigments, namely bone black and lamp black. Wyrsch (1732-1798) in his posthumously published treatise (1838) mentions three blacks, i.e. bone black, ivory black, and peach black.

Notes
1. The position of vermilion on palettes of the 17th century is described in the palette recommended by Roger de Piles in his painting treatise,Les Premiers Elémens de Peinture Pratique, Paris, 1684. See also Arthur Pope, The Language of Drawing and Painting, Cambridge, Mass., 1949, p. 130; W. G. Constable, The Painter's Workshop, London, 1954, pp. 122-123. De Pile's palette is reproduced in F. Schmid,The Practice of Painting, London, 1948, figs. 26 & 27.
2. The palette described by de Piles does not contain blue, but, of course, it was a palette primarily set for flesh tones. Blue was used in special circumstances, such painting a dress, draperies or sky in landscapes. In this case, a separate palette was usually set up for those passages. Many French 18th century artists (Nattier Vien, Duplessis, Drouais) did not place blue or green on their palettes. Also on the palette of John Trumbull, who was trained in England and France, we find no blue and green (see Theodore Sizer, The Works of Colonel John Trumbull, New Haven, 1950, pp. 101-105).
