Bigender Flag

Bigender Flag: A gender identity under the polygender, nonbinary, and transgender umbrella terms. ... The latter is a form of genderfluid identity, and may involve only two distinct genders, or it may involve "shades of gray between the two." The two genders of a bigender person can be the two binary genders, female and male.

Bigender Pride (Purple, light pink, light blue, cyan, and blue - Bigender people.   This is one of the most popular bigender flags.  I am not entirely certain of its origins nor the definitive meaning of its colors, but an educated guess would be that white represent trans* identity, light pink and shades of blue might represent femininity and masculinity, and purple represents the mixture of masculine and feminine identities because blue and pink make purple.)
