About Color Name Finder

Free color name finder tool that identifies the name of any hex color code instantly. Enter any of the 16.7 million possible hex colors (#000000 to #FFFFFF) and get the closest matching color name from a curated database of over 1,500 named colors — including CSS/HTML standard colors, Pantone-style names, and design-industry color names. The tool uses a perceptual color distance algorithm to find the best match, shows you the exact match percentage, displays a large color swatch with the input and matched color side by side, and provides the color's RGB, HSL, and CSS values for easy use in code. Perfect for designers, developers, and anyone who needs to communicate color names precisely. 100% browser-based, no signup required.

Frequently Asked Questions

How does the color name finder work?▾

The tool uses a database of over 1,500 named colors. When you enter a hex code, it calculates the perceptual distance between your color and every named color in the database using a weighted RGB distance formula that accounts for how the human eye perceives color differences. It then returns the closest matching name. If your exact hex code exists in the database, you get a 100% match.

Does it cover all possible hex colors?▾

Yes. There are 16,777,216 possible hex colors (#000000 to #FFFFFF). While no database names all of them, this tool matches ANY hex code to the closest named color from its 1,500+ name database. The match percentage tells you how close the match is — 100% means an exact match, and anything above 95% is visually very close.

What color names are included?▾

The database includes all 148 CSS/HTML named colors (like 'coral', 'teal', 'salmon'), plus over 1,350 additional named colors from design, fashion, and color science — names like 'Burnt Sienna', 'Electric Violet', 'Seafoam Green', 'Champagne', and 'Midnight Blue'. This gives much more descriptive and specific names than basic CSS colors alone.

What is a hex color code?▾

A hex color code is a 6-character code preceded by '#' that represents a color using the hexadecimal (base-16) system. The first two characters represent red (00-FF), the middle two represent green (00-FF), and the last two represent blue (00-FF). For example, #FF0000 is pure red, #00FF00 is pure green, and #0000FF is pure blue. There are 16.7 million possible combinations.

Can I search by RGB values instead of hex?▾

This tool accepts hex codes directly. To convert RGB to hex: each RGB value (0-255) maps to a two-digit hex value (00-FF). For example, RGB(255, 128, 0) becomes #FF8000. You can also use our Color Code Converter tool to convert between RGB, HEX, HSL, and other formats.

Is this tool free and private?▾

Yes, completely free with no signup. All color matching happens instantly in your browser — no data is sent to any server. The entire color name database is loaded locally, so the tool works offline after the page loads.
