The early 20th-century artist Robert Delaunay began painting at a pivotal moment in art history, namely during the chemical industry revolution, when the number of pigments available on the market increased. Today scientists are trying to solve the mystery of the painter’s colours, his purples in particular. One of the objectives of this research is to generate knowledge essential to conserving the works.
