Cosmicflux

According to Gender wiki (currently at Cosmicflux - Gender Wiki), Cosmicflux is a gender identity that fluctuates between femininity and masculinity, neither and both, but never feeling wholly man or woman. This is originally from a Tumblr post from Sunny, which describes the colors of the flag: purple - stars - lack of gender; blue - moon - femininity; green - eclipse - a mix of masculinity and femininity; yellow - sun - masculinity; purple is repeated at the bottom of the flag, giving 5 stripes.

The colours of the flag posted by Sunny on Tumblr are:

purple: #d19cff - blue: 9cd7ff - green: bbff9c - yellow: fff49c

The description fits into non-binary, gender-fluid and genderflux definitions, making it a Fluidflux-related identity.
