The Color of Sound - High-speed Photography Captures the Color of Sound Waves | Photography Friend

In fact, they are "colors of sound waves". Photographers cover a layer of thin membrane on a tiny loudspeaker, then drop pigments on it and play music. The thin membrane will vibrate according to the waveform of the music and the pigments above it will dance accordingly. Because the pigment drops are only a few millimeters high, their complex movements cannot be observed by the naked eye. The photographers use high-speed cameras to capture these wonderful moments, forming photographic works like rainbow sculptures.
