Typical color palette for the Roman inspiration might be something like red, white and gold. I wanted to avoid to being literal and boring so I decided to pick colors from Roman paintings. I found several paintings from the Met and the internet. Unfortunately, I do not have the titles of most works.
Wall painting: Polyphemus and Galatea in a landscape, from the imperial villa at Boscotrecase, Metropolitan Museum Of Art, New York This is the one that I was most inspired by.
And these are my colors and prints.
