What is Color Name Finder?

Color Name Finder helps you identify the closest named color for any HEX or RGB color value. Whether you're a designer looking to make your code more readable or a developer wanting to use semantic color names, this tool instantly matches your color to the nearest named color from comprehensive databases.

Why Use Named Colors?

Using named colors in your code offers several benefits:

Readability

"Tomato" is easier to understand than "#FF6347"

Maintainability

Named colors make code reviews and updates simpler

Communication

Share color choices with non-technical team members

CSS Compatibility

147 CSS named colors work in all browsers

Two Color Databases

Choose from two comprehensive color databases:

CSS Colors

147 Standard Colors

Standard web colors recognized by all browsers, including classics like "Red", "Blue", "Coral", and "SkyBlue"

Browser-native support
Production-ready
Universal compatibility

Extended Colors

1500+ Descriptive Names

Comprehensive database with descriptive names like "Dusty Rose", "Ocean Blue", "Champagne", and "Terracotta"

Creative naming
Design documentation
Evocative descriptions

Accurate Color Matching

Industry Standard Algorithm: The tool uses the Delta E 2000 (CIEDE2000) algorithm, the industry standard for measuring perceptual color difference. This ensures the matched color name truly represents how humans perceive the color, not just mathematical similarity.

CIEDE2000 is the most accurate color difference formula available, accounting for the non-uniformities in human color perception. It's used across printing, manufacturing, and digital design industries.

How to Use Color Name Finder

Enter Your Color

You have three ways to input a color:

Type HEX - Enter a HEX code like "#FF5733" or "FF5733"
Type RGB - Enter RGB values like "255, 87, 51" or "rgb(255, 87, 51)"
Use Color Picker - Click the color preview box to open the visual color picker

View the Match

The tool instantly displays:

Color Name - The closest named color (e.g., "Tomato")
Match Score - Percentage showing how close the match is (100% = exact match)
Delta E Value - Technical color difference measurement (0 = identical)
Color Values - HEX and RGB values of the matched named color

Frequently Asked Questions

What is Delta E and why does it matter?

Delta E (ΔE) is a metric for measuring the perceptual difference between two colors. A Delta E of 0 means the colors are identical. Values under 1 are imperceptible to most people, 1-2 are barely noticeable, and values over 10 indicate clearly different colors.

This tool uses Delta E 2000 (CIEDE2000), the most accurate standard for human color perception.

ΔE 0-1: Imperceptible Perfect

ΔE 1-2: Barely Noticeable Excellent

ΔE 2-10: Noticeable Good

ΔE 10+: Clearly Different Fair

What's the difference between CSS and Extended databases?

The CSS database contains 147 standard named colors that work in all web browsers (like "Red", "Coral", "SkyBlue"). The Extended database includes over 1500 colors with more descriptive names like "Dusty Rose", "Ocean Blue", "Champagne", and "Terracotta" - perfect for design documentation and creative projects.

Feature	CSS Colors	Extended Colors
Total Colors	147	1500+
Browser Support	Native	Reference Only
Use in CSS	Direct use	Use HEX/RGB values
Best For	Production code	Design documentation

Why doesn't my color show 100% match?

A 100% match only occurs when your color exactly matches a named color in the database. Most custom colors will show a high percentage (90-99%) indicating a very close match. The similar colors section helps you find alternatives that might be closer.

Understanding Match Scores: A 95%+ match means the color difference is barely perceptible to the human eye. Even 85-94% matches are considered excellent for most design purposes.

Can I use the color names in CSS?

Yes, all 147 colors in the CSS database are valid CSS color keywords. You can use them directly in your stylesheets (e.g., color: tomato;). Extended database names are for reference and documentation - use their HEX or RGB values in code.

CSS Named Colors Example

/* CSS Named Colors - Direct Use */
.button {
    background-color: tomato;
    color: white;
    border: 2px solid coral;
}

/* Extended Colors - Use HEX/RGB */
.card {
    background-color: #F5E6D3; /* Champagne */
    color: #2C5F7C; /* Ocean Blue */
}

How accurate is the color matching?

The tool uses the CIEDE2000 algorithm, which is the industry standard for color matching used in printing, manufacturing, and design. It accounts for how human eyes perceive color differences, making it more accurate than simple RGB distance calculations.

Simple RGB Distance

Mathematical Approach

Basic Euclidean distance
Ignores human perception
Less accurate results

CIEDE2000

Perceptual Approach

Industry standard algorithm
Matches human perception
Highly accurate results

Is my color data saved or shared?

No. All color matching happens entirely in your browser. Your colors are never uploaded to any server. History is stored locally on your device using browser storage.

100% Privacy Guaranteed:

All processing happens client-side in your browser
No data transmission to external servers
History stored only in local browser storage
No tracking or analytics on color searches
Clear history anytime to remove all data

Why do some colors have unusual names?

The Extended database includes creative and descriptive names from various sources including X11 colors, Pantone-inspired names, and descriptive terms. These names are meant to be evocative and memorable, helping designers communicate colors more effectively.

Gem-Inspired

Ruby, Sapphire, Emerald, Amethyst

Nature-Inspired
