INAH has been working on a Palenque preservation project in Chiapas for four years. They have restored four buildings within the Palenque main palace. They have uncovered a fragment of the original red paint on House D confirming the roofs of the palace were painted red. The red pigments for the paint were a mixture of minerals including iron oxide. The red paint was discover in the 1960’s and then covered one with cement to preserve it. And it was not recorded.
