Frequently Asked Questions
Where does the list of color names come from?
All 147 official CSS extended color keywords, like "CornflowerBlue" and "MediumSeaGreen" — the exact same standardized named colors browsers recognize when used directly in CSS.
How is the "nearest" match determined?
By the straight-line (Euclidean) distance between your color and each named color in RGB space — the named color with the smallest distance is shown as the closest match. This is a simple, common approach, though it doesn't perfectly account for how the human eye perceives color differences.
Will the exact color I enter always have a matching name?
Only if it's one of the 147 named colors exactly — for any other color, this tool finds and shows the closest named color along with exactly how different it is.
Is my data sent anywhere?
No — the entire lookup happens locally in your browser using JavaScript, so nothing is ever sent to a server.
