Color Name Finder: Get the Closest Color Name from Hex, RGB, or HSL

Ever had a hex code like #FF5500 and wondered what to call it? Or needed a human-readable name for a color in your palette? The Color Name Finder gives you the closest matching color name from multiple lists — Basic, HTML, X11, and NTC (1500+ names) — so you can document, discuss, or label colors by name instead of code.

Design scenario: Your brand hex is #E07C24. Is it “tangerine,” “orange,” or something else? The tool shows the closest name from each list plus a perceptual distance so you can pick the best fit.

What is a Color Name Finder?

A color name finder takes a color code (hex, RGB, or HSL) and returns the closest matching color name from one or more predefined lists. Because most hex codes don’t have an exact name, the tool uses perceptual color distance (Delta-E in Lab color space) so the suggested name matches what the eye sees.

The Tooladex Color Name Finder supports hex (e.g. #FF5500 or FF5500), RGB (e.g. rgb(255,85,0)), and HSL (e.g. hsl(24,100%,50%)). You get the closest match from Basic, HTML, X11, and NTC lists, plus extra NTC alternatives so you can choose a more specific or creative name.

Why Use a Color Name Finder?

Design & documentation — Name colors from a picker or brand hex for style guides, palettes, or design specs.

Accessibility & specs — Refer to colors by name in discussions or requirements (e.g. “use coral for highlights”).

Code & CSS — Decide between a named color (e.g. coral) and a hex value when writing or refactoring CSS.

Content & UI — Label colors in catalogs, filters, or product descriptions (e.g. “Tangerine” instead of #FF9966).

Branding — Give brand colors consistent, memorable names across teams and tools.

How the Color Name Finder Works

  1. Enter a color — Type a hex code (#FF5500 or FF5500), RGB (rgb(255,85,0)), or HSL (hsl(24,100%,50%)). Or use the built-in color picker to choose a color; the tool updates the name results as you pick.
  2. See the preview — A large color preview swatch shows the exact color you entered so you can confirm it’s correct.
  3. Get closest names — For each list (Basic, HTML, X11, NTC), the tool shows the closest name, its hex, and a distance value. Lower distance = closer perceptual match.
  4. Browse more NTC names — Up to 8 additional NTC matches are listed so you can pick a more specific or alternative name.

Name Lists Explained

Basic — A small set of simple names (e.g. red, blue, green). Best when you want a broad category.

HTML — Standard HTML/CSS color names (e.g. coral, tomato, crimson). Familiar to web developers.

X11 — X11 color names, the basis for many web color names. Slightly larger set than HTML.

NTC (Name That Color) — A large set of 1500+ names. Best when you want a specific or creative name (e.g. “Tangerine,” “Bittersweet”).

What Does Distance Mean?

Distance is how far your color is from the named color in Lab color space (perceptual).

  • 0 = exact match
  • Smaller values = closer match
  • Larger values = the name is only a rough fit

Use distance to judge how well a name fits. For example, a distance of 2 might be “very close,” while 15 might be “in the same ballpark but not precise.”

Examples

Hex input: #FF5500

  • Basic: Orange
  • HTML: Orange Red
  • X11: Orange Red
  • NTC: (closest name + extra alternatives)

RGB input: rgb(59, 130, 246)

  • Closest names from each list (e.g. Basic: Blue, HTML: Royal Blue) plus hex and distance.

Using the picker — Click the color picker, choose a shade, and the text input updates to hex; name results update automatically.

Frequently Asked Questions

What color formats are supported?
Hex (e.g. #FF5500 or FF5500), RGB (e.g. rgb(255,85,0)), RGBA, and HSL (e.g. hsl(24,100%,50%)). The tool normalizes 6-digit hex without # automatically.

Why do different lists give different names?
Each list has a different set of named colors. Basic has few names; NTC has 1500+. The closest name in each list can differ (e.g. “red” in Basic vs “coral” in HTML) because the lists don’t contain the same colors.

Can I use a color picker?
Yes. The Tooladex Color Name Finder includes a color picker; when you choose a color, the input updates to hex and name results update automatically.
