Hofmann, Rabitsch, Malissa, Aceto, Uhlir, Griesser, Calà, Agostino, Fenoglio 229 Painter D used a mixture of indigo and orpiment to paint green areas. Lead white is added to achieve lighter tones, orpiment is added for more yellow-green tones. Orpiment and lead white are confirmed by XRF, indigo by FORS. The particles of orpiment can be seen under the microscope. In accordance with the other artists painter D used red lead as red pigment and a mix- ture of madder and lead white as pink colour. The violet parts are a mixture of ultramarine blue, Egyptian blue, madder and lead white. The painter mixed his choice of blue pigment with madder and lead white. Brown parts are painted with earth pigments. Yellow areas are mostly painted with orpiment eventually with the addition of yellow ochres.
