// $palette is an iterator on colors sorted by pixel count

// an extractor is built from a palette
$extractor = new ColorExtractor($palette);

// it defines an extract method which return the most “representative” colors
$colors = $extractor->extract(5);



// we set a white background so fully transparent colors will be added as white in the palette
// pure red #FF0000 at 50% opacity will be stored as #FF8080 as it would be perceived
$palette = Palette::fromFilename('./some/image.png', Color::fromHexToInt('#FFFFFF'));
