It resembles a color wheel stretched into a band: colors travel in one direction and cycle over time. It works well when color itself is the focus of a background or decoration.
Set `mode` to rainbow for the full spectrum, or custom to cycle through three chosen colors. Change `angle` to rotate the direction of the gradient (default 0°, range -180–180°). Increase `scale` to fit more color cycles across the viewport (default 1, range 0.1–10). `speed` controls the cycle rate (default 0.05, range -1–1).
This generator fills the canvas and needs no input beneath it. Small text can be hard to read over rapidly changing colors, so leave a nearly uniform area where text will sit. Check whether the color bands already provide enough emphasis before adding more decoration.
When to use
Use it to show a rainbow or custom color set, create a flowing color backdrop, or display a stretched color wheel. Avoid it in tight areas where text contrast matters.
