audible color is an audio-visual instrument. Sound is generated based on color detected by a 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. Color detection and sound generation were created and are controlled using Processing code.
