title: Why Google Maps Polyline strokeColor always black?
body: <p>I have already draw some trajectories in Google Maps Api. But I want to give a different color to each trajectory. The problem is that the color always is black even when strokeColor is not '#0000'. Any ideas about what is happening? Here is my code:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;meta name="viewport" content="initial-scale=1.0, user-scalable=no"&gt;
  &lt;meta charset="utf-8"&gt;
  &lt;title&gt;Simple Polylines&lt;/title&gt;
  &lt;style&gt;
     html, body {
      height: 100%;
      margin: 0;
      padding: 0;
    }
    #map {
      height: 100%;
    }
  &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;div id="map"&gt;&lt;/div&gt;
  
  function initMap() {
  
      var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 10,
        center: {lat: -12, lng: -77},
        mapTypeId: google.maps.MapTypeId.TERRAIN
      });
  
  
      var aristas = map.data.loadGeoJson('aristas.geojson');
      var aristasPath = new google.maps.Polyline({    
        path: aristas,
        geodesic: true,
        strokeColor: '#FF0000',
        strokeOpacity: 1.0,
        strokeWeight: 2
      });
  
  
      aristasPath.setMap(map);
    }
  &lt;/script&gt;
  </code></pre>
