What did the Greek colony look like?

As a rule, the Greek colony was located on the seashore. The fortified, newly built city, which was built by the colonists, became the center of the new polis. Such colonies maintained close trade and cultural ties with Greece. Therefore, the appearance of the inhabitants, their structures, buildings in everything resembled the Greeks.
Even their gear and the hull of the ship, the Greek colony painted blue and blue shades. This is how the Greeks avoided unpleasant encounters with sea pirates.
