These are mountain bike trails tagged with a mtb_scale (1= green, 2 = blue, 3= red, 4+ = black). The colors only displays when zooming in, so they do not disturb the general view of the map. There is an untagged piece of route in the middle, so the difference should be clear.

The oneway arrows are always displayed, though. The tiny path on a brighter green background is a technical practice pitch.
