Color of trails on map

When I draw a map, it defaults to a red line. When I use the map, it tracks me with a red line. It is difficult to distinguish the map red line from the trail I am making, which is also red. I can make a map on my computer using a purple or green line. I can download them to my phone for using and see the purple line. When I go to navigate, it changes the purple back to red and I have the same problem seeing it. This also makes it hard the person viewing my Lifeline to know where I have been and where I am going
