What is a Color Name Finder?

A color name finder takes a color code (hex, RGB, HSL) and returns the closest matching color name from one or more lists (e.g. HTML/X11 color names, NTC). Because most codes don't have an exact name, the tool uses perceptual color distance (Delta-E in Lab space) so the name matches what the eye sees.

The Tooladex Color Name Finder uses the color-namer library and supports hex (#FF5500), RGB (rgb(255,85,0)), and HSL (hsl(24,100%,50%)). Results are shown from Basic, HTML/X11, and NTC (1500+ names) lists, with the closest match first and distance so you can judge fit.

How it Works

• Enter a color — Hex (#FF5500), RGB (rgb(255,85,0)), or HSL (hsl(24,100%,50%)). With or without # for hex.
• Matches are computed — Your color is compared to every named color in each list in Lab space; the smallest distance is the closest name.
• See closest names — For each list (Basic, HTML/X11, NTC) the closest name and its hex and distance are shown. Lower distance = closer match.
• More NTC matches — Up to 7 additional NTC names are listed by similarity so you can pick a more specific or alternative name.

All processing runs in your browser; no color data is sent to a server.

Name Lists

• Basic — Small set of simple names (e.g. red, blue, green).
• HTML / X11 — Standard HTML/CSS color names (from the X11 list). Shown together because they usually return the same closest match.
• NTC — Large set (1500+ names) from the "Name That Color" list; best for specific or creative names.

Use Cases

• Design — Name a color from a picker or brand hex for documentation or palettes.
• Accessibility — Refer to colors by name in specs or discussions.
• Code — Choose between named colors (e.g. coral) vs hex in CSS.
• Content — Label colors in catalogs, filters, or UI (e.g. "Tangerine" instead of #FF9966).
