Indig describes non-binary people who present with a combination of masculine, feminine, and androgynous features. It's a loose term and can be used by any non-binary person that does not feel like any of the more specific terms fit them.
Indig is a term from the pallet system of non-binary gender presentation. It's used to describe non-binary people's gender presentation without having to use the binary language like "masculine" or "woman-aligned". It is similar to the lesbian terms "butch" and "femme". The term was designed to be used along side the galactian alignment system, but can be used by any non-binary person. For example a non-binary person presenting with masculine, feminine, and androgynous features who is feminine-aligned could call themselves indig-lunarian.
The flag was designed by Tumblr user Elfiot, the coiner of the term, in January 2018.
