How to leave the Google map like this?

Yes, it is possible. There is a very useful tool for this here (link) where you can change whatever you want, and then export a JSON that you can pass to the options object of the GooGle Maps builder. An example:

styles: [{
    "stylers": [{
      "hue": "#ccff00"
    }, {
      "saturation": -100
    }]
}],

jsFiddle: link

The official documentation for setting styles is here .

The maps allow a very wide customization. I do not necessarily know how you want to display to let you know exactly which properties to change. I'll leave here a well explained tutorial in Portuguese, posted to Tableless and Google's own styling documentation , I hope it helps. There is not much mystery
