Abstract: The study of pigments is of fundamental importance for authentication and restoration purposes of painted artworks. To this aim reflectance spectroscopy has been widely studied on samples and in a number of real cases. A number of valuable efforts have been dedicated to this quest; however, the identification of a pigment on a painting surface by means of reflectance spectroscopy appears to be possible only in very few cases also due to the fact that artist materials are often mixed. In this paper we review a number of relevant works and present results on a new set of test samples especially produced for exploring the possibilities of reflectance spectroscopy on pigment mixtures. We also include a case study of a real painting.
