Did the Romans distinguish between black and blue? Or, more generally, what do we know about their color system?
I was wondering because many of the modern Roman languages use either Arabic or Germanic words for blue and I faintly remember my Latin teacher saying that Romans referred to the sky both at day and at night as "black". Here some examples:
- Italian: azzurro ("Arabic"), blu ("Germanic")
- French: bleu (there is also azurer = dye in blue)
- Spanish: azul
- Catalan: blau
