236 The miniatures of the Vienna Genesis: colour identification and painters’ palettes F painted backgrounds in a variety of violet to blue shades. The artist used yellow ochre for yellow and light brown tones. He mixed yellow ochre with lead white. Sometimes small amounts of ultramarine blue seem to have been added. On light brown areas, highlights were painted with lead white and yellow ochre. Shades were applied with a brown earth pigment. An earth pigment and lead white are confirmed by XRF, yellow ochre by FORS. Dark brown colours were painted with brown ochre and a reddish brown earth pigment. Painter F used carbon black for shades and contours. The hair of Joseph’s brothers was painted in this way on folio 19, page 38. The black paint was identified as carbon black by FORS. On some areas like the boots, the first layer is painted with a reddish brown earth pigment. XRF spectra indicate an earth pigment, possibly umber. Carbon black is applied on top. Blue-grey colours are a mixture of indigo and lead white as confirmed by XRF (lead white) and FORS (both pigments). Painter F also used mixtures of indigo, lead white, Fig. 41: Miniature on folio 19, page 37, Joseph meets his brothers.
