Fuschiahemaec (formerly tyriangender) is a gender in the hemospectrum system related to the fuchsia caste of trolls from the webcomic Homestuck. It can be defined as a fuchsia troll kingender, a gender related to the fuchsia caste’s societal role, a gender related to the aesthetics associated with fuchsia trolls, and/or a gender connected to royalty/power, some degree of femininity, and the ocean (particularly to deeper areas and to the creatures that dwell there).
This term was originally coined as "tyriangender" on the Tumblr blog mogai-headcanons on August 28, 2018. The original flag was created at the same time.
It was later revamped with a new name and flag by the same individual on his other Tumblr blog neopronouns on November 10, 2020.
