How to Use the HEX to Color Name Converter
When you're working on a design or writing code, a HEX code like "#3498DB" doesn't tell you much about what the color actually looks like. This tool converts your HEX code into RGB values, then compares it against a list of standard CSS color names to automatically find the closest match.
The comparison works by calculating the Euclidean distance between RGB values — essentially the straight-line distance in color space. A distance near 0 means an exact match, while a larger number means it's an approximation. Even without an exact match, you'll see the closest named color along with the actual RGB difference, which is useful for describing colors in design docs or team discussions.
Whether you're doing web development, sharing UI design mockups, or writing a brand color guide, this converter lets you communicate colors by name instead of raw HEX codes. It also automatically recognizes shorthand 3-digit HEX codes (like #39D).
Frequently Asked Questions
It converts your HEX code into RGB values, then calculates the RGB distance to every color in a standard CSS color list to find the closest match.
Standard color names are a limited set, so exact matches are rare. In that case, the tool shows the closest approximate name along with the actual RGB difference.
