History : During the 1950-1960 years, the American artist Mark Rothko uses red lithol in several of his works. He offers a series of paintings done with a palette of shades of this red pigment at Haward University in 1962. The works were installed in a bright room of the university. Over the years, the bright colors of the paintings turned darken to black. The specialists figure it out that the high brightness the paintings were subjected was responsible of the degradation of the pigment. The paintings were moved to a less exposed room in 1979. However, the damage on the paintings is considered as irreversible. The red porto is a reproduction of red lithol with better light hold. Pigment preparation made by Ocres de France in 2016.
