Created by the South Korean sound artists GRAYCODE and jiiiiin, #include red is a large-scale audiovisual installation and performance piece that explores ideas of synaesthesia (the relationship between what we hear and what we see) through the inherent frequencies within the visible spectrum and colour as a vocabulary. Examining how different visual and auditory stimuli relate by substituting sound and image, the duo’s first collaboration began with the simple question of “what does the colour red sound like?”
