Change marker icon color

Use setIcon:

marker.setIcon('http://maps.google.com/mapfiles/ms/icons/green-dot.png');

Or as part of marker init:

marker = new google.maps.Marker({
  icon: 'http://maps.google.com/mapfiles/ms/icons/green-dot.png',
});

Valid marker icon filenames are:

• Blue: blue-dot.png
• Red: red-dot.png
• Purple: purple-dot.png
• Yellow: yellow-dot.png
• Green: green-dot.png
