Browse this CSS named colors list with all 148 standard names, RGB, HSL values, and live previews. CSS supports predefined color names (e.g. red, steelblue) instead of HEX or RGB. This tool lets you look up names vs. HEX/RGB and convert between them.
Look up a name to get its value, or enter a value to find the closest CSS color name—handy when writing styles or building themes.
Enter or select a CSS color name (e.g. tomato, dodgerblue); the tool shows the corresponding HEX, RGB, and a swatch for confirmation and copy.
Enter HEX or RGB; the tool finds the closest standard CSS color name (if any) and may show difference or similarity, so you can choose between name and value.
Some tools let you browse all CSS colors by letter or category and copy names or values for use in code.
Usually the basic and extended color names from the W3C standard; the exact set matches the tool’s list and browser support.
There are only a finite set of names; custom colors often have no exact match. The tool may show the closest name and value for reference.
CSS color names are case-insensitive; the tool may display them in lowercase for easy copy-paste.
