How does the color name finder work?

The tool calculates the perceptual distance between your input color and every color in its database using the Delta-E formula, then returns the closest match by name. This ensures results reflect how humans see color differences, not just raw number differences.

Where do the color names come from?

The database includes standard CSS named colors, common design and paint color names, and an extended set of descriptive names used in web design tools and color libraries.

Will the named color always match my input exactly?

Not necessarily â€” the tool finds the closest named color, not an exact match. Most custom colors do not have an official name, so the result is the nearest approximation in the database.

Can I use CSS color names in production code?

Yes. CSS supports 140+ named colors (like 'tomato', 'steelblue', 'goldenrod') fully in all browsers. However, for precise brand colors you should always use HEX or RGB values rather than relying on named colors.
