Usage notes

 * Since it is used of the sea at sunset, some scholars think this word meant deep red, but others are sceptical that Homer meant the sea or oxen were red/wine-colored. Some speculate Homer may have had blue wine, but the word is elsewhere used of oxen. Eleanor Irwin suggested it indicated a dark surface reflecting light like wine in a goblet. Michael Clarke suggested it was meant to evoke not just the appearance of wine but its effects (e.g., when Achilles is at the "wine-dark" sea, he is intoxicated with grief).
 * For other hypotheses ― such as the geology of the Peloponnesus sea being filled with minerals that would raise the pH of diluted (as was Greek custom) wine to appear more bluish, and well as romantic notions of how the Greeks saw color — see Wine-Dark Sheep: Ancient Color in a Modern Greek Odyssey by Alana R.
