Synesthesia Pride Flag
As a synesthete myself, I made a flag!
Synesthesia is a "concomitant sensation", which is usually considered as a neurodivergent condition that one type of sense/stimulation can cause or evoke another subjective sensation or perception. A person with synesthesia is called a synesthete.
For example, a synesthete may "feel" colors upon actually colorless words, letters, numbers or patterns. Others might "taste" music and words, "see" the shapes of sounds and smells, etc. In the case of "sequence-space synesthesia", one tends to imagine or visualize ordinal sequences (usu. numbers, like dates, months, years, or mathematical calculations), as if they are in the space around, in a particular sequence/ configuration. In the case of "mirror-touch synesthesia", one might subjectively feel the similar sensations of other people, upon seeing them.
Synesthesia does not equal to delusion. Most synesthetes are totally aware that the synesthetic perceptions are not based on reality. For example, as for my grapheme-color synesthesia, I'm clear that the characters I see on books and screens are actually achromatic. It's like a layer of faint tint, a mixed perception - it arises out of intuition or even subconsciousness, but does not conflict with the mind of reason. Often if needed, it can be turned down.
The respective meanings of each color are below:
A variant, added another half of symmetrically inverted colors:
The Synesthesia Symbol is designed to resemble a "≈", denoting approximation, and syntony/resonance between different senses.
The outer rhombus-shaped frame represents the limits of the physical world, and one's place within their integral, inner perceptions. The wave-like pattern breaks the frame from the middle, signifies how synesthesia challenges the known, conventional ways to perceive the world.
