About Color Name Finder
Color Name Finder looks up the official CSS named colour that is closest to any hex code or RGB value you enter. It compares your colour against all 148 standard CSS named colours using Euclidean distance in RGB space — the same method design tools use for colour matching — and shows the result alongside the exact hex, RGB, and HSL values of your input. Useful for designers who need to know what a colour is called, developers writing CSS without a colour picker, and anyone curious about the name behind a hex code. 100% client-side, no uploads, no tracking.
