Pick the output format (Hex, RGB, or HSL) and choose a palette constraint to keep results visually coherent: Pastel clamps saturation to a soft range and lightness high; Vibrant maximises saturation around mid-lightness; Dark and Light push lightness to the ends. Useful for placeholder UI, design exploration, identicon-style coloring, or seeding test data. All generation runs in your browser — no API, no upload, no rate limit.","category":"color","categoryName":"Color","keywords":["random color generator","random color online","random hex color","random rgb","random hsl","random pastel colors","random vibrant colors","random dark color","random light color","color palette generator free","crypto random color","secure random color","random color picker"],"badge":"Generator","url":"https://toptool.io/random-color","inputs":[{"type":"number","key":"count","label":"Count","defaultValue":5,"min":1,"max":50,"step":1,"help":"How many colors to generate (1–50)."},{"type":"select","key":"format","label":"Output format","defaultValue":"hex","choices":[{"value":"hex","label":"Hex (#RRGGBB)"},{"value":"rgb","label":"RGB"},{"value":"hsl","label":"HSL"}]},{"type":"select","key":"palette","label":"Palette","defaultValue":"any","choices":[{"value":"any","label":"Any"},{"value":"pastel","label":"Pastel"},{"value":"vibrant","label":"Vibrant"},{"value":"dark","label":"Dark"},{"value":"light","label":"Light"}],"help":"Constrain saturation and lightness to a visual style."}],"outputs":[{"key":"list","label":"Colors","multiline":true},{"key":"swatches","label":"Preview","multiline":true},{"key":"css","label":"CSS array","multiline":true}],"invocation":{"webUi":"https://toptool.io/random-color","api":null,"notes":"Currently invoked via the web UI at `webUi`.
