148 of 148 colors shown. Click any color to copy its hex value.
Why This Tool
CSS defines 148 named colors (like cornflowerblue, tomato, rebeccapurple). When you have a HEX or RGB color and want to know its closest CSS name — or you want to browse all named colors — this tool matches any input color to the nearest CSS named color by visual distance.
How It Works
Enter a color in HEX, RGB, or HSL format. The tool calculates the distance to all 148 CSS named colors and shows the closest matches ranked by similarity. You can also browse the full list of named colors, sorted by hue, lightness, or name.
