Historical Colors are authentic recreations of paint colors that have been in use for hundreds of years and were considered essential to the working palettes of past masters. They have been recreated in a safe, reliable form, meeting the conservation requirements of fine artists. Great pains were taken to ensure that they shared the working properties of their predecessors. Contemporary artists can now explore the profoundly distinct qualities of historically significant colors while enjoying the advantages brought about by modern chemistry.
