Complete Guide: Color Name Finder
Everything you need to know about using this tool effectively
The Color Name Finder takes a hex color code and finds the closest named color from the CSS named colors list. It compares your input against all 147 standard CSS color names and returns the nearest match along with the color difference. All processing happens in the browser.
This tool calculates the Euclidean RGB distance between your input color and every CSS named color. The closest match (smallest distance) is returned as the result. The tool shows both your input color and the named color side by side.

The CSS named colors list includes 147 standard names like 'cornflowerblue' and 'tomato'.
Not every color has a close named match. The tool finds the nearest one.
Named colors are useful for readability in CSS and documentation.
The RGB distance gives a rough sense of how close the match is.
How does the tool find the closest color?
It calculates the Euclidean distance in RGB space between your input and every CSS named color. The color with the smallest distance is the closest match.
How many named colors are there?
The CSS specification defines 147 named colors, including standard names like 'red', 'blue', and 'green', plus extended names like 'cornflowerblue' and 'darkolivegreen'.
Is my data sent to a server?
No. All lookup happens in your browser. Nothing is transmitted.
What if no name is close?
The tool always returns the closest match by distance, even if the difference is large. Use the distance value to judge whether the match is acceptable.
Can I use the named color in CSS?
Yes. CSS named colors work in all modern browsers. Use the name directly in your stylesheet (e.g., color: cornflowerblue).
