Alterous Attraction

Alterous attraction is a form of tertiary attraction that is described as not being entirely platonic or romantic. It typically constitutes a level of emotional closeness usually more than what is considered normal for an entirely platonic relationship, but does not fall into what would be considered to be a romantic relationship.

Alterous attraction is very similar to queerplatonic attraction.

Flag
The alterous flag was made in 2016 by Tumblr user Alterous-Albatross. According to Alterous-Albatross "The yellow stands for platonic. The gray stands for the gray area between romantic and platonic attraction. Pink represents affection. Red represents romantic." The red and yellow are muted to show that it is not entirely platonic or romantic.
