About Color Name Finder

Color Name Finder matches a hex color to the closest of the 147 CSS named colors, using a weighted RGB distance that roughly tracks how different colors look.

It also resolves a name to its hex value. It runs in your browser.

How to use it

  1. Enter a hex color like #3366cc.
  2. See the nearest name, how far off it is, and the next closest names.
  3. Or type a name to get its hex.

Common questions

Why is the nearest name sometimes a surprise?

The CSS palette has gaps. A color between two named colors will snap to whichever is closer, which may not be the name you expected.

What does the distance number mean?

A rough measure of how far the input is from the named color. Zero is an exact match; small numbers are visually very close.

Which palette is used?

The CSS Level 4 named colors, including rebeccapurple and both gray and grey spellings.

Does anything leave my browser?

No. The tool runs entirely on this page.
