History : pigment preparation designed by the Société des Ocres de France in 2016. During the 1950s and 1960s, the American artist Mark Rothko used lithol red in several of his works. He offers a series of paintings produced with a palette of shades of this red pigment at Harvard University in 1962. The works were installed in a bright room at the university. Over the years, the bright colors of the paintings will darken until they become black. It turned out that the intense luminosity to which the paintings were subjected was responsible for the degradation of the pigment. The paintings were moved to a less exposed room in 1979. However, the damage to the paintings is considered irreversible. Port red is a reproduction of lithol red with better lightfastness.
