title: Filter Hex Colors
body: <p>I have a huge list of diffferent hex colors (>6500) and I want to remove colors which are very dark and colors which are very bright.</p>
  
  <p>How can I do this?
  Is there a specific charachteristic in the bright and dark hex color codes which I can use to filter them out? Do I need to convert them to integers..?</p>
  
  <p>Thank you!</p>
