Hi,
I don't understand what you are dealing with. The scheme is stored in the: iGO / Content / scheme. If you have nothing there, you will see the Default scheme.
To change the scheme in the iGO, go to Settings / Navigation View / Map Appearance / Day Map Colors & Night Map Colors.
The planned route always has a different color than the other roads. If you really have the route and the other roads the same color, try changing the scheme. For your idea I attach 2 pictures of what the planned route looks like (red and orange). Other roads are yellow. Color combinations vary in each scheme. You can even change colors yourself ... here... [Only registered and activated users can see links. ]
