JOSM and .kml polyline colour editing

[Bob Hawkins]

I copy here a post from OpenStreetMap Forum>Editors, to which I have received no answer:
I have found the presence of Public Rights of Way .kml files in JOSM to be very useful for comparative purposes.  One drawback is that they appear as grey polylines.  I cannot see a facility to change colour, and wonder if anyone knows differently?  A colour key is present with a hexadecimal value as an attribute, but changing that has no effect.
NOTE: I have changed the colour codes in Notepad to no effect, either.
