Hello Lorenz,
As I could understand you are looking for a method to change Google map’s color. If you had working with WordPress then I think installing a simple plugin as available at http://nullednet.com/?s=google+map and many other sites was sufficient. Any ways, you can prefer http://gmaps-samples-v3.googlecode.com/svn/trunk/styledmaps/wizard/index.html?utm_medium=twitter for the best solution. I have also tried it, hence can confidently say it’s really worth. With the help of various available options your can customize the map as per your desire and also find the source code of it. Hope it would be helpful for you.
