Colours track

Good morning,

can anybody explain the colour in the Track, blue, blue/red red pointed?

Blue line: Kurviger’s calculated route between the waypoints.

Green (dotted) line: connection between the waypoints (not too useful in my opinion).

When importing GPX files I recommend this options (to only have the red and blue line):
