COLOR TOOL · CLIENT-SIDE
Color Name Finder
Find the closest named CSS color for any HEX or RGB value. Search 140+ named colors.
How it works
- ● Enter a HEX code (e.g.
#ff5733) or a color name. - ● The tool calculates Euclidean distance in RGB space against all 148 CSS named colors.
- ● The closest match is shown with its swatch, name, and distance score.
- ● Distance of 0 = exact match. Under 15 = visually indistinguishable.
Why use named colors?
Named colors improve code readability and are easier to remember than HEX codes. They are defined in the CSS specification and supported by all modern browsers. When you need to reference a color by name, this tool helps you find the closest match.
Frequently Asked Questions
What are CSS named colors?
CSS named colors are 148 standard color keywords defined in the CSS specification, such as "tomato", "cornflowerblue", and "crimson". They provide human-readable color names that can be used in CSS instead of HEX or RGB values.
How does the distance score work?
The distance is calculated using Euclidean distance in RGB color space. A lower distance means a closer match. A distance of 0 means an exact match with a named color. Distances under 15 are usually visually indistinguishable.
Can I search by color name?
Yes. Type a CSS color name like "tomato" or "navy" into the input field and the tool will show its HEX value and swatch. You can also enter a HEX code to find the closest named color.
