You might have already noticed this one if you are a frequent Google Maps user. In the latest version of Google Maps, Google is introducing a new color scheme, an updated typography and an improved layout that helps users to easily identify popular places on the map.
Previously, Google Maps was only showing the names of popular places on the map but with the new update, Google is implementing a new color scheme that will enable users to easily locate the places with high traffic and as you can see in the image above, places like Suria KLCC and Quill City Mall is colored in yellow which indicates that the location is an 'Area of Interest'

According to Google, they are using a specific Algorithm to highlight areas of interest on the map. You can check out the new Google Maps look on the web or through the Android or iOS app.
