Alterous attraction is a form of emotional attraction. It describes a feeling that is not necessarily platonic/queerplatonic, but also is not romantic in nature. For some it may be in between romantic and platonic attraction, and for other it may be completely separate from the romantic/platonic distinction.
An alterous crush is known as a mesh or a hush, although the terms are not widely used. Alterous attraction is most commonly associated with the color light blue. One who does not experience alterous attraction may identify as a-alterous, analterous, or nonalterous.
The term was first introduced in approximately 2015. Since then, it has been variously used for a pull toward emotional closeness or intense feelings that may or may not have any relation to the romantic/nonromantic binary. Since 2016, some definitions of alterous have been criticized for implying than platonic or nonromantic feelings are inherently weaker than romantic ones.
The alterous flag was made in 2016 by Tumblr user Alterous-Albatross. According to the introduction post, "The yellow stands for platonic. The gray stands for the gray area between romantic and platonic attraction. Pink represents affection. Red represents romantic."
Another proposed Alterous flag features three of the same stripes from Tumblr user Alterous-Albatross original flag, but includes a blue-grey stripe instead of a grey stripe to match other alterous identity flags. As before, the yellow stands for platonic. The blue-grey represents alterous attraction itself and how it exists somewhere in the gray area between platonic and romantic attraction. Pink represents affection, and red represents romance.
A third proposed Alterous attraction flag was created by FANDOM user Zer0Rebel4. it features 7 stripes, and a hexagon in place of a heart to symbolise that it is not romantic, but also not platonic. the colours are dark blue for alloalterouses (those who experience alterous attraction), light blue for greyalterouses (those who rarely experience alterous attraction), dark violet for nonalterouses, light violet for demialterouses (those who experience alterous attraction to those theyre close to), lavender for alterous attraction, and black for the spectrum of alterous attraction.
