The custopronominal flag was coined by Cryptocrew on February 9th of 2021. Dark green represents countries and locations, light green represents unity and community, dark blue represents language and speech, light blue represents peace and joy, off-white represents writing and pronoun usage, white represents the gender spectrum, black represents the lack of gender, dark purple represents connection between pronouns and genders, while light purple represents disconnect between pronouns and gender.
Custo- comes from the word custom as these pronouns are custom to specific locations or languages.
