Flag of Greece of alternating blue and white - or silver - stripes on (several centuries-old) Kallergis' coats of arms is well documented, no depiction of the above described pattern (with the nine stripes and the cross) survives. The stripe-pattern of the Greek flag is visibly similar to that used (though with different colors) in several other flags that have appeared over the centuries, most notably that of the British East India Company's pre-1707 flag or the flag of the United States.

The land version of the national flag was to be used by ministries, embassies, and in general by all civil and military services, while the sea flag was to be used by naval and merchant vessels,
