An alternate flag was created and submitted to Ask-Pride-Color-Schemes on October 22, 2019 by a now deactivated tumblr user.<ref>[https://archive.is/sNe85 Alternate Iso flag, Archived]</ref> The blue, purple, and pink represents masc, fem, and people who may be a mix of both. The greyscale gradient represents attachment or intensity of gender, from white (entirely [[Agender]]) to dark grey (strong attachment).
Two tweaked Isogender flags were created by Tumblr user Noname-Nonamorous on August 24, 2021 from Beyond-MOGAI-Pride-Flags' design.<ref>[https://noname-nonamorous.tumblrarchive.comis/post/660369039404761088/tweaked-isogender-flagsfG5ml Noname-Nonamorous' Isogender flags, Archived]</ref> The flag took the original Isogender flag and adjusted the colors, made to look less bright and easier on the eyes. One of the flag features a disk symbol, coming from how Iso, the shortening of Isogender, is also a disk file type.
