Color Name Finder
Identify exact and nearest color names from hexadecimal color codes with RGB distance matching.
Run tool
This color name finder identifies exact and nearest color names for hexadecimal color codes. When you enter a hex value, the tool parses the red, green, and blue components and matches them against an internal palette of named colors. If your color code corresponds directly to an entry in the palette, the exact name is presented. If there is no exact match, the tool compares your color to each palette color and returns the closest named shade. The tool accepts standard six-digit hex codes as well as shorthand three-digit hex notations, automatically expanding values like #fff or f00 into full six-character codes. A missing leading number sign is added automatically during evaluation. If you leave the input field empty, the tool uses a default blue shade (#3498db) to show sample naming details. You can inspect the closest palette match alongside a calculated comparison value for quick reference.
Instructions
- Enter or paste a hexadecimal color code into the input field, such as #3498db, 3498db, or #abc.
- If you leave the color input empty, the tool processes the default hex color #3498db.
- Submit the form to evaluate the color.
- Review the returned exact name (if available), the nearest palette color name, and the calculated comparison value.
Examples
- Input '#ff0000': matches the exact color name 'Red' in the built-in palette with zero distance.
- Input '#3498db': returns the nearest palette name 'Curious Blue' alongside the computed color distance.
FAQ
Can I enter hex colors without the hash symbol?
Yes. If the leading '#' is omitted, the tool automatically prepends it before parsing the hex color value.
What happens if my hex code does not match an exact color name?
When there is no identical RGB match in the palette, the tool compares your color to each palette color and returns the closest match.
Are three-digit hex codes supported?
Yes. Three-digit shorthand notation such as #f00 or abc is automatically expanded to six digits (like #ff0000 or aabbcc) prior to evaluation.
What is the default value if no color is provided?
If the color input is left blank, the tool defaults to the hex code #3498db.
