Color Name Finder

Have a HEX code and want to know what to call it? This finder compares your color with two name lists — the 148 CSS named colors that work in HTML and CSS, and the 949 names from the xkcd color survey, where over 200,000 people named colors in their own words — and returns the closest names by perceived difference (CIEDE2000). Switch to Name → color to look up a name such as "dusty rose" or "teal" and get its code.

How to use this tool

1. Type or paste a color: HEX, rgb(), hsl() or any CSS color.
2. Choose whether to search CSS names, xkcd names or both.
3. Read the nearest names and their ΔE2000 — the smaller, the closer.
4. Or choose Name → color and type a name to get its HEX and RGB.

Formula

nearest name = the entry with the smallest ΔE₀₀ (CIEDE2000) from your color, both converted from sRGB to CIELAB (D50)

ΔE₀₀ below about 1 is invisible to most people, 2–3 is a small but visible step, above 10 the colors are clearly different. Gray/grey spellings and the duplicate pairs aqua/cyan and fuchsia/magenta are shown once.

Example

Searching #3B7DD8 finds the CSS name steelblue #4682B4 at ΔE2000 5.24 — close, but visibly different — and the xkcd name clear blue #247AFD at only 2.86. An exact keyword like #FF6347 comes back as "tomato #FF6347" with ΔE2000 0. In reverse, "tomato" gives the CSS color #FF6347 first and the xkcd survey's tomato #EF4026 second — the crowd picked a deeper red.
