On OSMAND maps I notice some areas which are covered with pink color.
Example 1: in Germany the area between Bingen and Koblenz and a wide range left and right of the Rhine river.
Example 2: All the water surface of the lake Garda in upper Italy.
The pink color does not appear at zoom level 2 km and higher. It shows up at zoom level 1 km and lower.
Why are these areas overlaid with pink? The color hides all other colors of land features like forests, grassland, fields, etc.
I find this is very annoying. I imagine that the pink color is to indicate a special kind of area. But which one?
And, as almost nobody knows what it means, I think it should not show up on maps.
