———————————————————————————
Please use a gradient blue color showing the route from start to finish. Starting with dark blue and ending with light blue. This is very useful when planning a round trip. Then there is no confusion if the current equal blue line indicates the way to follow or the opposite way when looking on the map. You can then clearly see a darker blue line (where you are driving) crossing a lighter blue line where you will drive later on (on the way back). Hope this is clear enough and easy to implement.
