How are the dominant colors calculated?

The tool uses fast 3D RGB color quantization and Euclidean distance clustering to identify the most prominent distinct color families across the image.

Are my uploaded pictures stored anywhere?

No. The image is drawn to an in-memory HTML5 Canvas directly on your computer. Nothing is transmitted across the internet.

Can I export the palette directly to CSS?

Yes! Click "Copy CSS Variables" to get a clean :root { --color-1: ... } code snippet ready to paste into your stylesheet.
