Unless someone has changed it, the color= option uses the coded rules;
e.g. color=gyr uses G_make_gyr_fp_colors(), which has the hardcoded
0=white rule.
IOW this bug/feature is in the various G_make_*_colors() functions in
libgis.

libgis.
Note that the 'r.colors rules=gyr' version has had the '0 white' removed
already. Presumably we can now remove this pre-NULL code from libgis as
well?

I have already removed that in 5.7.
