Indigender

Indigender is a sort of umbrella term meant to represent any gender or genders that are affected and/or exclusive to a culture or race of indigenous people.

Anyone of indigenous culture may use this identity. It is not for any one specific indigenous culture, but nor is it for anyone who is POC. It is mean to be "adjacent to a gender specific to one's culture, but that does not fit all roles or aspects of that gender."

Flag
The blurple on the right represents the culture that is closest to your gender, and the yellow representing you actual gender that is adjacent to it. The flag was created by an unknown person, and was coined by someone who wishes to remain anonymous.
