Random color on javascript

Here is a simple function that creates a random color.

  function randomColor() {
      $letters = '0123456789ABCDEF'.split('');
      $color = '#';
      for (var i = 0; i < 6; i++ ) {
          $color += $letters[Math.floor(Math.random() * 16)];
      }
  }

  $('a').hover(function() {
      randomColor();
      $(this).css('color', $color);
  });

After adding this code every link on your site will randomly change color after you hover it.

Thank you.
