With the Europe City Map Premium 2016.2H we introduced a new roadtype “Unpaved roads”. Because this roadtype is not known by the old renderer (xMap 1.20.1 and earlier) these roads will be displayed in bright green.
Workaround to change the colour of these roads
You need to edit the profile file. Depending on your used profile it is silkysand.ini, sandbox.ini or gravelpit.ini in your xMap or xServer /conf/ Folder.
Unfortunately the classic Profile is hardcoded and can not be edited manually.
These values:
[config.streeti.colorbytype]
10=65280
[config.streetf.colorbytype]
10=65280
must be changed to:
[config.streeti.colorbytype]
10=9879248
[config.streetf.colorbytype]
10=9879248
Alternatively you 
can download configuration files of the 1.22.0.1 version here and copy them to your conf folder, overwriting the existing ones.
There is a small typo in the post:
config.streeti.colorbyte should be config.streeti.colorbytype
That is right and i corrected it in the post. Thank you for your feedback.
