title: Grab all colors of a webpage with python
body: <p>I'd like to find an efficient way to extract some sort of color-palette (a list, or something else) from a given page-url with python. What I want is to take all background's colors, colors of the titles and of all the other elements. </p>
  
  <p>I've already seen here [<a href="https://stackoverflow.com/questions/18801218/build-a-color-palette-from-image-url">Build a color palette from image URL</a> ] that it is possible to take a palette from an image, but what about a page?</p>
