you need to landscape the hill side. the shutters are very small on the large left windows, i would get larger ones there and add them to the side window

I might go with the darker blue on your shutters for the large sides and then leave the trim white. I might also add shutters to the windows on the side of the house to get a more consistent look. Good luck!

Hi there - a dark blue gray is wonderful against red brick and very colonial . . .something like bm smoke gray http://www.benjaminmoore.com/en-us/paint-color/smokegray
or a classic wedgewood blue gray on all the siding and trim.

then, do a shutter one shade deeper, to match darker garage doors . . bm almost black . . and try a sunny yellow front door . .
