Black roof and white siding and get rid of the that don’t fit like all of the ones on the right part of the house and if you want the ones on the left they need to be larger

Rid your home of its "shudders"...here's why.

I vote for the dark gray because...that color will allow you to widen the trim (white paint) around the windows, which will give you the "definition" you'll need sans shutters.

When you re-side, paint the downspouts the same color as the siding. Downspouts are not a design feature and should "disappear" into the background color.

SO glad you will be replacing the (current) awful window directly above the front door (what were they thinking???).

Thank you both. They chose the dark gray. I presented them with my first option of removing the shutters and widening the trim around the windows (see below). But they are pretty adamant about keeping the shutters. I am definitely going to have them size them the height of the trim at the very least. We also added a red door to tie in their red shed (not shown)
