For my own house I choose to paint the shutters in Benjamin Moore's Metallic Silver. It is not actually silver or metallic but just a pretty gray color. It was inspired by two houses/buildings that I often drive by in Bedford, NY.
Both of these places have a different look that wasn't really captured in the photos. I think the natural daylight and sun give them both a really beautiful look.
One exterior that I have loved for a few years (as have tons of other people!) is Miles Redd's house. Love the blue color of his front door. It was a custom mixed color so I could only try to find something similar.
