I see. I still feel sorry for the OP. Nowhere in the US are we required to paint our garages the same color as our houses. Except in the most highly controlled residence areas. But perhaps in Germany, people just feel better when the houses and garages match. Or that is a legal building requirement. I can understand that.

I've also explained to Europeans why it is that so many houses are seen floating away in floods and hurricanes in the US. They are surprised to discover that so many Americans live in trailers located on flood plains and next to rivers. Well, we do. We are a mysterious people.
