Copenhagen-based designers Momo Miyazaki and Hideaki Matsui created Audible Color, an audio-visual instrument that uses simple physical gestures for an intuitive interaction between sounds and colors. Both designers are students at the Copenhagen Institute of Interaction Design (CIID), where they developed this playful sound project.
How it works: Pipettes are used to drip coloured water onto a clean white surface, and a webcam detects the colour of each drop. Software built using Processing translates the color to a corresponding musical note and plays an arpeggiated sequence based on the colors present.
FYI: The basic concept behind the project is that three base colours (red, green, and blue) correspond to three different notes (A, D, and F). When these base colors combine to make purple, teal, and brown, new notes (C, E, and G) are generated. The size of the drops also effects the volume and frequency of notes played, so we’re guessing an accidental spill just might blow your headphones.
