Stuff I’ve learned from Twitter and archived here for future reference.
First we’ll credit “v ness” and her response to attacks of a talented graphic artist representing Roman poets with dark skin:

My meagre contribution prompted some scholarly refs I want to save (image I posted was photographed and posted by Gareth Harney):

Armand D’ Angour quoted:
” I’m not too bothered, Caesar, to inspire your delight, Nor to determine whether, as a man, you’re black or white. Nil nimium studeo, Caesar, tibi velle placere, nec scire, utrum sis albus an ater homo.“
Catullus 93
While all agree that the b/w allusion here likely does not refer to skin but politics or sexuality, this led Rebecca Futo Kennedy to recommend the following readings:
