According to online sources, a user of an unspecified online site may have created the autosexual flag.
There are different versions of the autosexual flag, but in most cases, it consists of blue and gray horizontal stripes. Some flags also feature a red heart with an arrow around it in the middle.
To some, the blue may symbolize the relationship autosexual people have with themselves.
The gray may represent the asexual spectrum, as some autosexual people may identify with being on the asexual spectrum.
