title: Extract all colors from an image using colorgram
body: <p>I am willing to get all of the colors present in an image in python using colorgram. In the documentation they don't specifically say about this. Here is my code:</p>
  <pre><code>import colorgram as cg
  
  color_list = cg.extract(&quot;dot-img.jpg&quot;, 60)
  color_palette = []
  
  for count in range(len(color_list)):
      rgb = color_list[count]
      color = rgb.rgb
      color_palette.append(color)
  </code></pre>
  <p>I wrote 60 in cg.extract second argument. But I don't get 60 colors. Does that mean that colorgram returned me all of the colors present in the image?</p>
