Maybe Red Castle could be Mar-a-lago? It has a red/orange tile roof.
Great catch!
My ~only~ color reasoning was green golf courses, subtropical foliage, manicured gardens. Red, I’ve never been to NYC but see pictures with lots of red brick buildings. Plus, those commie-reds who voted hildebeast. I know they now label conservatives red, but it’s been red for commies most of our lives.
I did not know of the red roof but that makes sense to me. As I said earlier, I’m not convinced of this notion of mine. It just makes sense castles are residences since white castle is white house.
