This new look was announced on Google’s Blog in which they’ve made a bunch of changes to various aspects of Google Maps, such to the driving mode, navigation, transit, and have also given it a new coat of paint that makes it look slightly brighter and cleaner. Google claims these changes will help to highlight the information most relevant to each experience, such as making gas stations more visible when using Google Maps for driving.
According to Google, “We’ve also updated our color scheme and added new icons to help you quickly identify exactly what kind of point of interest you’re looking at. Places like a cafe, church, museum or hospital will have a designated color and icon, so that it’s easy to find that type of destination on the map.”
It seems that this fresh coat of paint and new colors won’t be limited to Google Maps. Google has also announced that these changes will be applied over the course of the next few weeks to all products/services that use Google Maps, so do keep an eye out for those changes.
