Original Greek statues were brightly painted, but after thousands of years, those paints have worn away. Find out how shining a light on the statues can be that's required to see them the way they were thousands of years ago.
Although it seems impossible to think that anything could be left to discover after thousands of years of wind, sun, sand, and art students, finding the long lost patterns on a piece of ancient Greek sculpture can be as easy as shining a lamp on it. A technique called ‘raking light' has been used to analyze art for a long time. A lamp is positioned carefully enough that the path of the light is almost parallel to the surface of the object. When used on paintings, this makes brushstrokes, grit, and dust obvious. On statues, the effect is more subtle. Brush-strokes are impossible to see, but because different paints wear off at different rates, the stone is raised in some places – protected from erosion by its cap of paint – and lowered in others. Elaborate patterns become visible.
Ultraviolet is also used to discern patterns. UV light makes many organic compounds fluoresce. Art dealers use UV lights to check if art has been touched up, since older paints have a lot of organic compounds and modern paints have relatively little. On ancient Greek statues, tiny fragments of pigment still left on the surface glow bright, illuminating more detailed patterns.
Once the pattern is mapped, there is still the problem of figuring out which paint colors to use. A series of dark blues will create a very different effect than gold and pink. Even if enough pigment is left over so that the naked eye can make out a color, a few thousand years can really change a statue's complexion. There's no reason to think that color seen today would be anything like the hues the statues were originally painted.
There is a way around this dilemma. The colors may fade over time, but the original materials – plant and animal-derived pigments, crushed stones or shells – still look the same today as they did thousands of years ago. This can also be discovered using light.
Infrared and X-ray spectroscopy can help researches understand what the paints are made of, and how they looked all that time ago. Spectroscopy relies on the fact that atoms are picky when it comes to what kind of incoming energy they absorb. Certain materials will only accept certain wavelengths of light. Everything else they reflect. Spectroscopes send out a variety of wavelengths, like scouts into a foreign land. Inevitably, a few of these scouts do not come back. By noting which wavelengths are absorbed, scientists can determine what materials the substance is made of. Infrared helps determine organic compounds. X-rays, because of their higher energy level, don't stop for anything less than the heavier elements, like rocks and minerals. Together, researchers can determine approximately what color a millennia-old statue was painted.
The color? Always something tacky.
Via Harvard, Colour Lovers, Tate, The Smithsonian, Colorado University, and Carleton.

Very very cool.
Now about all those old movies with white statues.....
I prefer them looking old, gray and weathered.
Very interesting. Thanks.
Wow! That is really cool!
Of course the second statue shown is not Greek—it’s the Prima Porta statue of the Roman emperor Augustus.
Good Lord, Red! What the hell was THAT for?!! Now I am blind!!
Since when has historical accuracy ever been a concern of Hollywood?
Headline should read
New technology reveals ancient Greeks had terrible taste in art.
But of course...would you have any Grey Poupon?;)
The ancient world was painted gaudy colors and probably more resembled this:
than anything we see in movies or textbooks.
“its the Prima Porta statue of the Roman emperor Augustus.”
Yes, but it’s in the Greek style and may have been sculpted by a Greek.
Thats been the general consensus of opinion as these (re)discoveries have become more widespread. But one is forced to consider how much of our taste for what is and isn't tacky is dictated by centuries of what we thought Greek/Roman art looked like. IOW, if the paints hadn't faded away, would we now be pooh-poohing marble white, empty eyed statues as bland and soulless?
