The latest research on the Elgin - or Parthenon - Marbles has been to look at the fragmentary remains of the paintwork which once covered the marble and made the sculpture vibrant to the beholder on the Acropolis.

Analysis of the colour scheme suggests a significant use of blue and purple pigments in the original scheme. That any of it has survived at all is, given its antiquity and the exposure and handling the sculpture has endured over twenty four or so centuries, a tribute to the quality of the materials used.
The research is set out by an article by the Daily Telegraph which can be seen at Elgin Marbles were painted in vivid hues of ‘Egyptian blue’ and purple
