These visible plinths often in anthracite unfortunately look terrible (at least on the rather modern new buildings). Plinth color matching the wall color is modern and looks much nicer to me.
As always, everyone here has their own taste. We deliberately painted the plinth anthracite, together with our anthracite gravel strip it looks absolutely great.
Overall, everything just has to be harmonious (roof color, house color, plinth). Red roof, white house, and anthracite plinth is of course not so harmonious.
