Chromesthesia

Chromesthesia or sound to color synesthesia is a type of synesthesia in which heard sounds automatically and involuntarily evoke an experience of color. For the purpose of disambiguation, this article will refer to this chromesthesia in inducer-concurrent terms used to describe other forms of synesthesia. With sounds inducing color concurrents, chromesthesia is more accurately termed sound-color synesthesia. Individuals with sound-color synesthesia are consciously aware of their synesthetic color associations/perceptions in daily life. Synesthetes that perceive color while listening to music experience the colors in addition to the normal auditory sensations that would be triggered in the average person. That is, the synesthetic color experience supplements, but does not obscure real, modality-specific perceptions. As with other variations of synesthesia, individuals with sound-color synesthesia perceive the synesthetic experience spontaneously, and without effort, and in a way that the individual learns to accept as normal within their realm of experience.
