Useful for describing colors in plain English, picking sensible Tailwind-adjacent names, or auditing whether a custom color is already close to a CSS keyword. The distance metric is Euclidean in RGB space — a cheap approximation of perceptual delta-E that's plenty accurate for matching at this granularity. The full 148-color list is bundled inline; no external lookup needed. Returns the top 5 candidates so you can pick the best fit.","category":"color","categoryName":"Color","keywords":["color name finder","closest color name","css color name lookup","hex to color name","rgb to color name","named color finder","color name picker","what color is this hex","find color name","color name converter","css named colors list","color naming tool"],"badge":"Lookup","url":"https://toolsly.tools/color-name-finder","inputs":[{"type":"text","key":"color","label":"Color","placeholder":"#3b82f6","defaultValue":"#3b82f6","monospace":true,"help":"Hex, rgb(), hsl(), or a CSS color name (returns itself if exact)."}],"outputs":[{"key":"preview","label":"Input preview","multiline":true},{"key":"name","label":"Closest CSS name"},{"key":"nameHex","label":"Closest CSS hex"},{"key":"delta","label":"Distance (RGB Euclidean)"},{"key":"candidates","label":"Top 5 candidates","multiline":true}],"invocation":{"webUi":"https://toolsly.tools/color-name-finder","api":null,"notes":"Currently invoked via the web UI at `webUi`.
