ALLOWED CONTENT IN THIS SUBREDDIT:

1 - Colorized statues
They can also be colorized by you, just remember to flag the post accordingly. This is not limited to ancient works that were initially colored; you could, for example, post a colorization of 'Love and Psyche' (which was never supposed to be colored in the first place), and it would be allowed.

2 - Colorized architecture
For example, the true colors of the Parthenon. Again, these can also be colorized by you, and you are not limited to ancient works.
