Color Name Lookup

Color Name Lookup turns a raw HEX or RGB value into a recognizable CSS color name. Instead of staring at a code like #4682B4 and wondering what it actually looks like, you get the nearest standard color name plus a live preview.

Paste any HEX or RGB value and the tool shows the closest CSS named color along with the color distance between your input and that match. It is handy for writing readable CSS, handing designs off between teammates, naming a color sampled from an image, or simply answering the question what color is this. You can also browse all 140+ standard CSS color names with their swatches to compare options.

Keep in mind that nearest-name matching is based on color distance, so the closest CSS name may differ slightly from your exact value rather than matching it perfectly. Everything runs locally in your browser, so your color values are never uploaded anywhere.
