Spectral Rainbow Frequency is about creating an experience akin to a certain type of synesthesia, as if all hues of colors comes, emerging and piercing through darkness accompanying the soundtrack.

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. The earliest recorded case of synesthesia is attributed to the philosopher John Locke, who, in 1690, made a report about a blind man who said he experienced the color scarlet when he heard the sound of a trumpet.
