Gradient API
Generate colour gradients and colour scales programmatically. Produce an evenly-spaced scale of N colours between two or more stops (interpolated in a perceptually smooth colour space — lab, lch, oklab, oklch — or plain rgb/hsl), get a single interpolated colour at any position between two colours, and build a ready-to-paste CSS gradient string (linear with any angle, or radial) from a list of stops. Colours accept hex (#f00, #ff0000) or CSS names (red, steelblue). Perfect for data-visualisation colour ramps, heatmaps, chart palettes, theme generation and UI backgrounds. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. Distinct from colour conversion / harmonious palettes (one base colour) and image palette extraction.
