Color Name Finder

Your color is compared to every standard CSS named color using straight-line, or Euclidean, distance between their red, green, and blue channels. The name with the smallest distance wins, and a distance of exactly 0 means the colors are identical.

The full set of standard CSS named colors, roughly 140 keywords. That includes the familiar ones like red, teal, and gold as well as newer additions such as rebeccapurple, and the gray and grey spellings which point to the same values.

Yes. Type a CSS color name such as teal or rebeccapurple and the tool resolves it to its hex value. When your input is a recognised name it also notes that below the result so you know it is an official keyword.

Six-digit hex like #ff0000, three-digit shorthand like #f00, an rgb() string, a plain comma-separated r,g,b triple, and any CSS color name all work. The leading hash on a hex value is optional.

It is the RGB-space gap between your color and the nearest named one, rounded to two decimals. Smaller means closer: a value in the low single digits is visually almost identical, while a large distance means the closest name is only a rough approximation.

CSS defines both spellings for several colors, and they map to identical hex values. When your color is an exact tie the tool returns the first match it encounters, so a mid gray reports the gray spelling.

No. The comparison is done in plain RGB, which is simple and predictable but does not model how the human eye perceives differences. Two colors with a small RGB distance can occasionally look a little further apart than the number suggests, especially among greens.

If the text is not a hex value, an rgb form, or a known CSS name, the tool shows a short prompt asking for one of those formats rather than guessing a match.

Yes. The lookup and the nearest-name search both run in your browser against a built-in color list, so nothing you type is uploaded.
