About this tool
Dynamic Rainbow is a free online visual effect. Rainbow bands undulate and scroll while the hue keeps cycling, switchable among wave, ring and beam modes. 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 sky scene will be displayed. The rainbow slowly appears from the sky, and the seven colors of the rainbow transition smoothly, producing a true spectral effect. Parameters such as rainbow arc, color saturation, and appearance speed can be adjusted.
The whole process is pure front-end animation. Canvas-based gradient filling simulates the spectral color of the rainbow, and transparency gradients are used to simulate the fade-in effect of the rainbow.
It is suitable for use as a sky-themed decoration, a dreamy atmosphere background, or simply appreciating the gorgeous beauty of the rainbow. The implementation principle is gradient filling and transparency animation.
Dynamic Rainbow is a visual effect that simulates the dynamic appearance of a rainbow in the sky. It renders the spectral colors of the rainbow in real time based on Canvas.
