About this tool
Color Pulse is a free online visual effect. Color breathing pulse effect with rhythmic motion. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
After opening the page, a full-screen color pulse effect will be displayed. The color will constantly change with the rhythm, spreading from the center to the outside to form ripples. You can use a microphone to input audio and let the colors pulse with the rhythm of the music, or you can use the built-in automatic rhythm.
The entire process is pure front-end animation, based on Canvas or CSS gradients, using the Web Audio API to analyze the audio spectrum and map frequencies to colors and diffusion radii.
Suitable for music visualization, party atmosphere decoration, or purely appreciating the rhythm of color. The implementation principles are fast Fourier transform (FFT) and color space mapping.
Color Pulse is a color-changing visual effect based on audio frequency or time rhythm, and full-screen colors pulse with the rhythm.
