Microscopic paint samples were collected from a light, pink flesh tone (forehead, sample X40) and a shadow tone (cheek, sample X39) from the Girl’s face to investigate stylistic and chemical differences. The paint samples were embedded in Technovit 2000 LC mounting resin (Heraeus Kulzer GmbH, Germany) and polished using a sample holder and Micromesh sheets up to grade 12000 (Micro-Surface Finishing Products Inc., Wilton, Iowa, USA) (33). A Zeiss Axio Imager.A2m microscope equipped with a Zeiss AxioCam MRc5 digital camera was used to examine the polished cross sections, before scanning electron microscopy–energy-dispersive x-ray analysis.
