Operation Manual

2.4.4 Colour scheme in tunnels

When entering a tunnel, the colours of the map change. All buildings disappear, large objects (such

as surface waters or forests) and empty areas between roads become black.

However, roads and streets keep their original colours from the daytime or night colour scheme

currently used.

After leaving the tunnel, the original colours return.
