Skygender is a gender that varies in clarity. On one day, it may be clear and easy to read and process, but then it may feel clouded over and become confusing the next day.
History
Skygender was coined by at least August 24th, 2014 by an unknown user via now-deleted tumblr blog MOGAI-Archive. The exact coining date is not known since the blog was deleted.
The skygender flag was designed by tumblr user pastelmemer, and the alternate by pride-color-schemes on tumblr. The main flag was designed by at least August 22, 2015 (via a post on DeviantArt blog Pride-Flags), and the alternate was designed by at least August 1 of 2016, though exact dates are not currently known for either.
