Flag of Sentan

The national flag of Sentan is a tricolor flag consisting of purple, green and grey colors. As one of the only countries in the world that has a purple-colored flag, the first Sentanese flag was designed at the dawn of the New Edo War. The flag’s top side was originally blue, but however, due to the lack of blue fabric dye, the flags made in the early 1930s have their top color was dyed purple.
