Color Name Finder
Given any hex, RGB, or HSL color, find the closest CSS named color out of the standard 148-color list. 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.
