	// example: create css stylesheet from image file
	checkErr := func(err error) { if err != nil { panic(err) } }

	f, err := os.Open("some_image.jpg")
	checkErr(err)
	defer f.Close()

	img, _, err := image.Decode(f)
	checkErr(err)

	palette, err := vibrant.NewPaletteFromImage(img)
	checkErr(err)

	for name, swatch := range palette.ExtractAwesome() {
		fmt.Printf("/* %s (population: %d) *\/\n%s\n\n", name, swatch.Population, swatch)
	}

output:

	/* LightMuted (population: 253) *\/
	.lightmuted{background-color:#cbc0a2;color:#000000;}

	/* DarkMuted (population: 11069) *\/
