How it works
K-means colour clustering
Samples pixels from your logo and groups similar colours together using k-means clustering — the same technique used in design tools to find dominant brand colours.
Tints & shades formula
Each extracted colour is mixed toward white (tints) and toward black (shades) in equal steps, giving you a complete 50–900 style scale for every brand hue.
Skip neutrals option
Whites, blacks, and near-greys dominate most logos. Toggle Skip near-white/black on to surface the actual brand accent colours instead of background fills.
100% private, zero upload
Everything runs in your browser via the Canvas API. Your logo never touches a server. Works offline once the page loads.
