Three works by the artist, two paintings with wooden stand and a wall painting were analyzed. Pigments were vibrationally identified from cross-section samples of the contemporary paints on wood Rio and Saludo and the wall painting Mental. The blue color Raman bands corresponds to cooper phthalocyanine. In the green areas, the Raman signals were ascribed to the azopigment acetoacetic arylide and copper phthalocyanine; the green color is then the result of a combination of the yellow and blue pigments. Raman bands in the pink areas were assigned to the azopigment beta-naphthol. The dark green color in the Saludo paint is due to a chlorinated copper phthalocyanine pigment. Other materials in the artworks were also identified: rutile (TiO2) in Saludo in white areas and calcite (CaCO3) in Mental and Rio. On this basis and taking into account the identification of the state of conservation a protocol for the preservation of the artworks Rio and Saludo can be assessed.
