Synesthesia is a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway.
People who report a lifelong history of such experiences are known as synesthetes.
Awareness of synesthetic perceptions varies from person to person. In one common form of synesthesia, known as grapheme–colour synesthesia or colour–graphemic synesthesia, letters or numbers are perceived as inherently coloured.
This series of graphics for an art exhibition is my attempt to present the theory by experimenting with light and texture through a mixed medium approach.
