title: I call random colors in my js but would avoid a selection
body: <p>I call random colors in my JS. It's working well.</p>
  <p>(this is for a follow cursor that randomly display a color on link)</p>
  <p>But some colors are too dark and I would like to avoid them.</p>
  <pre><code>   $links.on('mouseenter', function(e){
        var color = '#'+Math.floor(Math.random()*16777215).toString(16);
        var colorString = color;
        $('#whaouu').css('background-color',colorString);
     });
  </code></pre>
  <p>How can I avoid the darkest part of my colors?</p>
