color are in the image.
OPTIONS
-sort={frequency,rgb}
The -sort option determines the order in which the colors are listed in the output. frequency means to list them in order of how
pixels in the input image have the color, with the most represented colors first. rgb means to sort them first by the intensity of
the red component of the color, the of the green, then of the blue, with the least intense first.
The default is frequency.
-hexcolor
Print the color components in hexadecimal. Default is decimal.
