Vincent, Dirk If I might interject: exporting to .gpx and using that because I can change colour would take me backwards. I use .kml files now instead of .gpx because they retain the attributes of the polyline, in this case. I have arrived at a convoluted solution: to export to .gpx, open it, position it above the .kml layer and change the colour. I can view the attributes if I swap the layers. I hoped there might be a simpler way. My knowledge does not extend to creating my own Map Paint styles regrettably.
