This is a recommended color from SW for Mindful Gray…homburg gray. I would do this on the shutters and the garage doors and leave the wood door as is. The two middle windows shouldn’t have shutters as the won’t fit appropriately, but you are not painting the siding and the darker outlines of the shutters will show if you don’t replace what was there. Personally, would like the house with out shutters and would probably paint the siding and garage doors and have no shutters at all.

I would eliminate black for the sole reason that you do not have enough (or in some elevations any) black trim on the exterior for it to tie into.

We had a hailstorm last year and had to have our roof replaced. Where we live several houses were having their roofs replaced and our HOA calls for you to have the color “weathered wood”. We started noticing lots of roofs being replaced and the newer shingles are very speckled looking! a house that has a lot of variation in the brick can really look a little crazy if the roof is speckled also. I would just be really careful picking what looks like architectural shingles using sample pictures. If you call the roofing supplier or your roofer they should be able to give you addresses of the colors of shingles you’re interested in so you could actually drive to by that home and see the shingles on an actual home. We found it very helpful and the color “weather wood” is very different looking across different brands of roofing. We chose Malarkey brand their Legacy line in “Weathered Wood” color upgrading to the class 4 impact resistant shingles. you also might check with your insurance company because we paid a little extra to get the class 4 impact resistant shingle and we get a discount on our insurance. Just a few things I learned while picking Roofing last year!

Not a pro but the style of windows and house don't look well suited to shutters. However, if you keep them look into having them installed so they look like a better fit. For example, the shutters on the left are too far from the window edges. The shutters on the far right window look like they need to be wider. Each shutter should be half the window's width. Maybe the pros here can suggest something that fits the house better. It looks like a pretty house and setting.
