Frequently asked questions
How is closeness measured?▾
We use the redmean approximation — a fast perceptually weighted RGB distance that's a good middle ground between cheap Euclidean RGB and full CIEDE2000.
How many names are matched?▾
All ~140 CSS3 / X11 named colors that browsers natively support — the same list you can use directly in CSS like color: rebeccapurple.
Why are 'aqua' and 'cyan' identical?▾
They are. CSS keeps both names for legacy reasons; the matcher returns whichever scores first.
