Another one from back in March that I missed … they’ve detected traces of red paint on the Medici Venus’ lips:

• The Medici Venus Once Had Red Lips (Discovery.com)

Of course, we have long commented on colorizing of ancient statuary:

• The Golden Menorah on the Arch of Titus
• Exhibition: True Colors – Rediscovering Pigments on Greco-Roman Marble Sculpture
  Parthenon Colours
• Elgin Marbles in Colour
• Colouring Trajan’s Column?
• Colored Sculptures Again
• Painted Roman Statue

… etc. … I’m sure there are more …
