The origins and meaning of the genderqueer flag, which by its description includes all nonbinary people under one or more of the three colours:

gqid:

Note: The majority of followers who added their opinion in reblogs or in the recent poll decided they wanted the colors of lavender, white, and green to be kept, instead of my proposed lavender, black, green revision. Thanks for the input everyone! This is now the final design, not “proposed revision” as before.

The genderqueer pride flag is a Marilyn Roxie design, 3rd and final version created in June 2011, modified from version 1.0 in June 2010, and 2.0 in September 2010. The design is aesthetically similar to the gay and lesbian, bisexual, transgender, asexual, and pansexual flags; that is, horizontal bars of color with special meaning. The meaning of the colors in the genderqueer flag design are as follows: 

Lavender (#b57edc): The mixture of blue and pink (traditional colors associated with men and women, present on the transgender pride flag) as lavender is meant to represent androgynes and androgyny. Also represents the  “queer” in genderqueer, as lavender is a color that has long been associated with “queerness”, including gay, lesbian, and bisexual communities.

White (#ffffff): Meant to represent agender identity, congruent with the gender neutral white on the transgender pride flag.

Dark Chartreuse Green (#498022): The inverse of the lavender color; meant to represent “third gender” identity, i.e. those whose identities are defined outside of and without reference to the binary.

The three colors are not meant to indicate that any of these identities are entirely separate or opposites of one another conceptually; they are all interrelated as well as key concepts in their own right, and there are more concepts and variation of gender and sexuality present that tie into genderqueer identities than can be listed here. The purpose of the flag is to help create visibility for the genderqueer community and related identities.

Cheers,
