Medium to dark gray

dark gray

You have a great home with character - and a terrific roof line to accent. IMO I would go with a warm color - an actual color like red and bring it to all of your trim. Or go bold with black for all of your trim including windows like the insp pic below. Or go for a white trim, but beef up your trim so it shows. What is your favorite color? You have beige siding (at least on my monitor) so you have a wide variety of colors you can choose. Check out the BM visualizer and the affinity colors to see what you like best.

Blue/gray would be pretty. Or light blue.

For the trim, I think something very slightly darker than the house paint color would be nice. Repaint the side door and vents to match the house, and choose dark gray for the window trim and garage light.

I think it would be nice to emphasize the house #s too, maybe a dark gray backplate to frame them? On a very subjective note, I think it would look nice if you could square off the dog-eared garage upper corners and entrance, maybe even add a more substantial top trim piece for emphasis.

First thought is black.
