Sound-Color Synesthesia

For those with Sound to Color Synesthesia (or Chromethesia), heard sounds trigger the experience of certain colors. Like other forms of the condition, the experiences are automatic and involuntary.

Also like other forms of synesthesia, the association to certain stimuli are variant between each individual. However, research has shown that both synesthetes and non-synesthetes alike associate high-pitch sounds with bright colors, and low-pitch sounds with dark colors.

Narrow-band Chromethesia: Individuals report that certain musical notes evoke certain shades and hues of color.
Broad Band Chromethesia: Ordinary sounds elicit experiences of color i.e. a car horn, the sound of a pencil on paper, etc.
