Improvement: Colored highways, even in dark mode

[useross]

Motivation
In the normal view, highways are both drawn with a thicker line and highlighted in color.

In Dark Mode, highways are only drawn with a thicker line, but are not highlighted in color. This makes it harder to find your way around the map.

Improvement
Highlight highways in color in Dark Mode as well.

Are you using Google Maps or OpenStreetMap as map data source? For Google Maps I unfortunately cannot change this - the feature exists in the Google Maps SDK for Android, but it is not available in the free tier and therefore would cause significantly higher API costs. For OpenStreetMap I could probably influence the style a bit - though that would then make it less consistent between the two implementations.

I am using OpenStreetMap as data source.
It is really hard to get the overview in the dark mode - so if it is possible to adapt this, it would be nice.
