Archaeological museums often own collections of classical statues and architectures originally colored. Unfortunately, only tiny traces of these colors are still visible and what is left needs to be preserved carefully. Although it is complex to reconstruct their original appearance, institutions believe that it is also crucial to offer a correct understanding, training visitors’ eyes to recognise those original colors, also to avoid dangerous misunderstanding supporting ideologies. What matters are the shades of colors, their perception and their semantics. The reliability of digital reconstructions and the authenticity of digital experiences is crucial. Disappearing polychromy is also an amazing occasion to make visitors reflect on the diversity of these shades of colors, developing a new perception on European modern society, through these artworks.
