audible color is an audio-visual instrument. Sound is generated based on color detected by an ordinary camera. Red, green and blue correspond with certain music notes. When the colors are mixed, the resulting secondary colors produce different notes. The size of the colors influences the volume and frequency of the notes played. The ‘painting’ aspect is not restricted to water droplets from a pipette. Numerous experiments were performed using substances such as acrylic paint, food dye in milk with soap, and ordinary household objects. Each investigation created a new type of fun and easy gestural music-making. The work was designed by Hideaki Matsui and Momo Miyazaki.
