提问by adhitia hidayat
Does anyone know how to give a different color to each country in a google map?
有谁知道如何在谷歌地图中为每个国家/地区赋予不同的颜色？
e.g:
例如：

在世界地图上
Blue overlay to UK, then RED china...etc
蓝色叠加到英国，然后是红色china...等
I wonder if google provide API to give color to each country
我想知道 google 是否提供 API 来为每个国家/地区赋予颜色

Using Google Maps this is really not easy, as @oezi said you would need to build overlays of every country you want to color, which frankly sounds like a mess.
使用谷歌地图这真的不容易，因为@oezi 说你需要为你想要着色的每个国家建立叠加层，坦率地说，这听起来很混乱。
But if you don't need all of the functionalities of Google Maps, perhaps you can use a Map Chartfrom the fantastic Google Chart Tools(aka Chart API). You can check and tinker with a working example of a Colored Map (among some others) in the interactive Chart Wizard
但是，如果您不需要 Google Maps 的所有功能，也许您可以使用来自出色的Google Chart Tools（又名Chart API）的Map Chart。您可以在交互式图表向导中检查和修改彩色地图（以及其他一些）的工作示例
2017 UPDATE: This answer is quite old and as such the Map Charts API has been deprecated by Google. You can use the Geochartsfrom the Google Charts APIinstead:
2017 年更新：这个答案已经很老了，因此 Google 已弃用 Map Charts API。您可以使用Geocharts从谷歌图表API，而不是：

Hope this helps!
希望这可以帮助！

there is a possibility to change the map style. and there is a very nice interactive example here- but, as far as i can see, it isn't possible to change the style of a specific country using this, so you'll have to build your own overlays using polygons.
有可能更改地图样式。并且有一个非常好的互动的例子在这里-不过，据我所看到的，这是不可能改变一个特定国家采用这种风格，所以你必须建立自己的使用多边形覆盖。

First, find the shape file in .kml format. Tip: try googling "kml uk" or "kml china".
首先，找到 .kml 格式的形状文件。提示：尝试谷歌搜索“kml uk”或“kml china”。
Once you have the KMLfile, host it somewhere and then call it as a varinside your Google Maps API initMap like this:
拥有 KMLfile 后，将其托管在某处，然后将其作为varGoogle Maps API initMap 内部调用，如下所示：
var myCustomRegion = new google.maps.KmlLayer({
url: 'FULL_URL_TO_YOUR_SHAPE_FILE',
map: map
});
Now your shape is laid into your map.
现在您的形状已放置在您的地图中。
You can style the shape using the <LineStyle>and <PolyStyle>tags inside the KML file itself.
您可以使用KML 文件本身内的<LineStyle>和<PolyStyle>标签来设置形状的样式。
