In the late 19th century Armenian emigrants created several versions of national flag in France. The red-green-white flag (or according to W. Crampton the red-green-blue one) was used by the Armenian community during Victor Hugo’s funeral in 1885. In the version of the creator of that flag – father Leon Alishan - the colors of the flag symbolize the rainbow witnessed by Noah on top of Ararat. He also claims an interesting fact that in the Armenian religious calendar first Easter Sunday is referred to as “red”, the second as “green” and the white stripe on the flag symbolized unification of all colors of the specter.
The yellow-red-green and the blue-red-green flags also ascend to Leon Alishan (the latter was obviously inspired by the French tricolor).
