Color Name Finder

Find the name of any color — enter a HEX code to get the closest CSS / HTML color name, with its RGB values and how close the match is.

How to use

1Enter a HEX color code, e.g. #3A7BD5.
2See the nearest named color and a few other close matches.

How it's calculated

Colors are compared in the CIELAB color space (ΔE distance), which matches how different colors look to the human eye. ΔE below 2.3 is barely noticeable.

Frequently asked questions

Where do the names come from?

The 148 named colors in the CSS standard — names like SteelBlue and Tomato that work directly in HTML and CSS.

What does ΔE mean?

The perceptual difference between two colors. Under 2.3 is a just-noticeable difference; above 10 the colors look clearly different.

Can I use the name instead of the HEX code in CSS?

Yes — color: steelblue; works in every browser, but only when the match is exact (ΔE 0).
