RampenSau is a compact and efficient JavaScript utility designed to create dynamic color ramps using curves within the HSL (Hue, Saturation, Lightness) color model. Written in TypeScript and completely free of dependencies, it emphasizes performance and simplicity—making it an appealing tool for developers and designers seeking fine-tuned control over color transitions in their projects.

What sets RampenSau apart is how it interprets and renders curves to produce visually appealing gradient sequences. Users can define how colors shift over a spectrum, allowing for nuanced palettes tailored to specific aesthetics or data visualization needs. The function's curve-based generation unlocks possibilities that go beyond linear interpolations, offering more expressive and balanced control over hue, saturation, and light transitions.

Although lightweight, RampenSau offers a variety of input options and customization parameters, enabling users to preview and tweak their color ramp configurations directly. Whether integrated into a design system, used in charts and dashboards, or explored for experimental visuals, this tool presents a flexible, code-friendly approach to working with HSL-based gradients.
