Per this link, you can use a data:image URL containing SVG for the icon of a marker.

var $markerImage = document.querySelector('.markerImage'),
  markerImageSvg = $markerImage.innerHTML || '';
var marker = new google.maps.Marker({
    position: map.getCenter(),
    map: map,
    clickable: false,
    icon: {
      anchor: new google.maps.Point(16, 16),
      url: 'data:image/svg+xml;charset=utf-8,' + encodeURIComponent(markerImageSvg.replace('{{background}}', colors[0]))
    }
  });

proof of concept fiddle

code snippet:

function initialize() {
  var map = new google.maps.Map(
    document.getElementById("map_canvas"), {
      center: new google.maps.LatLng(37.4419, -122.1419),
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });

  var $markerImage = document.querySelector('.markerImage'),
    markerImageSvg = $markerImage.innerHTML || '';
  new google.maps.Marker({
    position: map.getCenter(),
    map: map,
    clickable: false,
    icon: {
      anchor: new google.maps.Point(16, 16),
      url: 'data:image/svg+xml;charset=utf-8,' + encodeURIComponent(markerImageSvg.replace('{{background}}', "#FF4847"))
    }
  });
}
google.maps.event.addDomListener(window, "load", initialize);

html,
body,
#map_canvas {
  height: 100%;
  width: 100%;
  margin: 0px;
  padding: 0px
}
.markerImage {
  display: none;
}
