The ancient Greek epic poem, the Iliad, does not explicitly describe Patroclus's skin color.
Ancient Greek literature often focused on character traits, actions, and relationships rather than physical descriptions. This is especially true for characters like Patroclus, who is primarily known for his loyalty to Achilles and his role in the Trojan War.
Therefore, we cannot definitively say what skin color Patroclus had based on the Iliad.
It is important to note that ancient Greece was a diverse region, and people of various skin tones lived there. However, the Iliad does not provide any information about Patroclus's ethnicity or physical appearance that would allow us to make assumptions about his skin color.
