Since this is only for a single property, it's better to not have a macro and
just write this out in StyleBuilderCustom.cpp

Anyway, as I said it's supposed that new color properties follow the same
pattern,
but we can create a macro later if needed.

 {% macro apply_counter(property_id, action) %}
 {% set property = properties[property_id] %}
 {{declare_initial_function(property_id)}} {
