We aren't certain about the actual coloration of most classical statues. The one thing that we are certain about is that most of them weren't the plain, pure white we see in museums today.
After hundreds of years of gradual, literal whitewashing of the roots of western culture, how can we reorient our understanding of classical sculpture, and, by entension, classical civilization itself? One potential idea would be to literally repaint iconic statues.
Much like the ancient human and humanoid skulls of the bone lab, classical sculptures are generally priceless artifacts. Thus, they are a prime situation for virtual reality. In VR, anyone can paint anything, and if they don't like how it turns out, they can start over. Digitally, there are infinite copies of any artifact once it has been scanned.
