Archaeologist Vinzenz Brinkmann has reconstructed the original painting scheme that colored many classical sculptures. The effect is startling. See the NYTimes, http://snipr.com/1sesr. This is the best collection of photos I could find, but it's short on information; plus, it's in Danish.

Hmm. That completely changes my outlook on Greek statues. If these were really the original colors and look, I have to be honest that I much prefer them as blank white.
