One tenant of classical idealism is the idea that Roman and Greek statuary embodied an ideal of pure whiteness. A lie and/or misconception modern sculptors perpetuated for hundreds of years by making busts and statues in polished white marble. But the truth is that both Greek statues and their Roman counterparts were originally brightly painted in riotous color.
Learning to see the past as it was requires us to put aside historically acquired blinders. This can be exceedingly difficult when our ideas about the past come from hundreds of years of inherited tradition, from every period of art history since the time of Michelangelo. But we must acknowledge this tradition as fabricated.
