API Reference / data-tools / color-string-to-hex

Resolve a human-friendly color string into a canonical hex value.

Accepts hex literals, CSS color names, RGB/RGBA strings, or descriptive phrases (e.g., "warm blue", "light forest green"). The service normalizes modifiers (light/dark/bright) and returns a #rrggbb string so downstream image APIs can rely on consistent color inputs.
