I don't really see any windows suitable for shutters in these photos.

Pretty home.

If you want light blue I would want a less bold shade.

BM Kentucky Haze

My taste would be more like this

BM Appalachian Brown. Bittersweet Chocolate is another black/brown.

You should try out colors on your own. I did these images at the BM site.

There are no spaces for shutters any where that I can see

The picture I’ve provided does not show the windows that will have shutters -they’re either not in the pic, or they’re shaded. I appreciate the comments. I too am thinking something less bold, and maybe even leaning towards green blue. That, or stained like the cedar columns will be. I just think the house needs a bit of color.
