Intergender: an intersex person whose gender feels connected, linked, influenced, or a result of being intersex. This term is used as a descriptor of one’s gender (e.g. an intergender trans woman) similar to how neurogender is a descriptor. Intergender is also used as a gender in of itself (e.g. hir gender is intergender). This is a well-established term in the intersex community.
I’m personally a minimalist when it comes to queer flag design. This design takes the Carpenter intersex flag and inverts the colours, to reflect how intergender is a complimentary term to intersex.
The colour fits nicely with how the ipsogender flag already does this (it replaces the ring with the Earth symbol). It also allows us to take flags with a design of intersex flag + <icon of other thing> and turn them into intergender flag + <icon of other thing>, like so:
