More visible color in map route

The route path shown on maps could be more evident if the colour where dark blue (as shown in Tesla navigator) instead of current light grey:

I have already created a PR (#54) for it but the initial implementation idea was to use the accent color of your app palette, and the accent color depends on your car paint color. So if you have a grey car (like I do) you get that grey that's not that visible. But if your car is red or blue, you get there as well a more prominent color.

But maybe in this context using the accent color doesn't make that sense.

Thanks.
(By the way, my car is dark blue, or maybe not because I've load a custom paint scheme)
