Gradient Lab
About
Gradient Lab renders a live animated gradient behind two control panels. Pick one of 32 modes, among them Mesh, Bands, Glass, Halftone, Smoke, Aurora, Plasma, Rays, Prism, and Vortex, or start from presets like Sunset, Ember Smoke, Reeded Glass, Molten Gold, and Stained Glass. The right panel sets the palette swatches and how many are active, with a Randomize palette button, then the shape and motion controls for the mode, such as noise scale, softness, warp, and flow speed for Mesh, and brightness, contrast, saturation, and grain. Export Video renders MP4 or WebM from 480p to 4K and up to 30 seconds, a still exports as PNG, and the settings live in the URL for sharing or copy out as a live embed.
