Improve the visibility of "Slope" line style
The "Slope" colouring mode for tracks is a great tool to better estimate the slope of a track. Together with contour lines and hill shading you quickly get a "3D impression" of your tour.
Compared to a simple blue line the track in slope mode is harder to oversee, and that's mostly because of the light green colour. In most maps, the woods are also displayed in a greenish colour, that's why the slope line style is hard to read, especially in direct sunlight.
I would appreciate
– using darker colours for better contrast on light backgrounds
– changing the colours of the "slope" line style in a way that they are easier to read, e.g. blue for flat parts (instead of green), green for downhill (instead of blue) and red for uphill. That's just a suggestion, maybe someone has a better idea.
– maybe letting the user choose a custom colour scale.
