@Sam Brown, I don't know if you were typing tongue in cheek with your headline "shudders" (instead of 'shutters'), but you bring up a good point! Read this brief article on "shudders" https://www.lifeofanarchitect.com/residential-architecture-101-shutters/

You might want to enhance your shutters before you decide to paint them.

Also I agree the front door should be your accent color to focus attention to the front entry and the shutters should be another color in addition to being sized right with shutter hardware (see link I posted).

I'm so glad you are able to spring into Spring in January!

PS, Consider widening your walkway and updating your landscaping. Let me find a pic for you. You will have a busy Spring updating your very nice home :)

Here is an insp pic with a nice wide welcoming walkway to the front door and large planting beds:

I like the Navy front door (dark Navy) too. How about black shutters?

I think the Navy goes with your siding and your brick. Something like the insp pic below

I like the dark blue best.

I would paint the shutters a darker version of the siding and use the navy on the door only.
