As of this morning, there were 55 relations with the osmc:symbol tag.
I changed them all to have the way color be the same as the foreground color.
I also added colour=* tag to ways where applicable.
That means that we now have a standard colour tag on ways (and not as before where about half of the ways had the colour tag, and the other half had the color tag…)
Hopefully, tomorrow’s Lovia’s map will have all the changes.
It’s already updates to last night, and some of the routes show there nicely. 
e.g. in the Carmel.
hikebikemap.de isn’t yet updated, hopefully it will update during the day, but all the changes should be there by tomorrow mid day.
Edit: hikebikemap.de is now updated. Here is an example.
