What is a Color Name Finder?

A Color Name Finder is a free online tool that identifies the closest CSS color name (like "Tomato", "Sky Blue", or "Medium Purple") for any color code. It searches through the CSS/X11 color database and finds exact matches or calculates the closest named color using color distance algorithms.

Why use color names?

  • Readability: color: tomato is easier to read than color: #FF6347
  • Memorability: Named colors are easier to remember
  • Communication: Easier to discuss colors with team members
  • Quick Prototyping: Faster than looking up hex codes
  • CSS Standard: All modern browsers support CSS color names

How does it work?

  • Enter any color (HEX, RGB, HSL) using the color picker
  • The tool searches the CSS/X11 color database
  • If there's an exact match, you'll see it immediately
  • Otherwise, it calculates the closest named color using RGB distance
  • View similar named colors for alternatives

How to Use Color Name Finder (Step-by-step)

  1. Enter Your Color: Use the color picker or type a HEX/RGB/HSL value
  2. View Results: See the closest CSS color name instantly
  3. Check Match Type: See if it's an exact match or closest approximation
  4. Compare Colors: View side-by-side comparison of your color vs named color
  5. Explore Similar: Browse similar named colors for alternatives
  6. Copy Name: Use the color name in your CSS code

Pro Tips:

  • Exact matches show "Perfect match!" with distance 0
  • Lower distance numbers mean closer color matches
  • Use named colors for quick prototyping, hex codes for precision
  • Check similar colors for alternative options
  • Named colors are great for documentation and communication

Understanding Color Distance

The tool calculates color distance using Euclidean distance in RGB color space:

distance = √[(R₁-R₂)² + (G₁-G₂)² + (B₁-B₂)²]

What the distance means:

  • 0: Perfect match (exact same color)
  • 1-50: Very similar (barely noticeable difference)
  • 51-100: Similar (noticeable but close)
  • 101-200: Somewhat similar (clearly different)
  • 200+: Different colors

Example:

  • Your color: #FF6B47
  • Closest: #FF6347 (Tomato)
  • Distance: ~10 (very similar)

Using Named Colors in CSS

Basic Usage

.element {
  color: tomato;
  background-color: sky-blue;
  border-color: medium-purple;
}

Advantages

  • ✅ More readable code
  • ✅ Easier to remember
  • ✅ Faster prototyping
  • ✅ Better for documentation
  • ✅ Supported in all browsers

When to Use Hex Instead

  • ❌ Need exact brand colors
  • ❌ Require transparency (use RGBA)
  • ❌ Need colors not in CSS database
  • ❌ Working with design systems

Combining Both

:root {
  --primary: tomato; /* Named for readability */
  --secondary: #4a90e2; /* Hex for precision */
  --accent: rgba(255, 99, 71, 0.8); /* RGBA for transparency */
}

Are color names case-sensitive in CSS?

No! CSS color names are case-insensitive. tomato, Tomato, and TOMATO all work the same.

Can I use color names with opacity?

Named colors don't support opacity directly. Convert to RGBA format: rgba(255, 99, 71, 0.5) for Tomato at 50% opacity.

What's better: color names or hex codes?
