Named color
Ultramarine Blue
This is the nearest match in the built-in list of named colors, at a distance of 29.88 in RGB space. It is the closest standard name, not an official name for your exact color.
- 1Enter a HEX color or pick it with the swatch.
- 2Read the named color next to yours, side by side.
- 3Check whether the match is exact or the nearest available name.
- 4Copy the name for your design tokens, brief or alt text.
#FF0000 is exactly Red, distance 0. #2563EB has no exact name in the list; its nearest entry is Royal Blue (#4169E1) at an RGB distance of about 30.3, so the tool labels it as the nearest match, not the official name of that blue.
- Matching uses straight-line (Euclidean) distance in sRGB space, which is fast and predictable but not perfectly perceptual; two colors at the same distance can look differently close.
- The list covers CSS keywords and well-known traditional names; commercial paint catalogues use their own trademarked names, which are not included.
- Gray and grey spellings both exist in the CSS list, mirroring the standard.
It is the straight-line distance between the two colors in RGB space. 0 is identical; small single digits are barely distinguishable; above roughly 50 the colors are visibly different.
About this tool
The Color Name Finder takes any HEX color and returns the nearest entry from a built-in list of 504 named colors: the 148 CSS color keywords plus traditional and widely published names. It is how you turn a bare hex value into something a human can say in a meeting: an exact name when one exists, and the closest standard name when it does not.
