What does their flag remind you of?
Let me make a couple suggestions, could be a reminder of slavery, or could be a reminder of arrangements of colors and symbols used by many for many different causes, over the years. It’s something of a Rorschach test. Your interpretation may reveal more about you than about them.
The Tsarist Russian Naval Ensign.
Has a lot of historical relevance in the region, as a lot of the Russo-Turkish wars for the Black sea were fought under that flag.
John Paul Jones served the Tsar as a mercenary under that flag.
