Three-colour blends
A two-colour gradient is fine, but a third stop in the middle opens up far richer transitions. This generator gives you three colour stops across a linear or radial gradient, previewed full-size, and outputs a single background declaration to paste in.
Painted, not an image
CSS gradients are drawn by the browser, so they stay crisp at any size and add no download weight. Everything is generated on your device with nothing uploaded.
