What color is the roof? To me this makes a big impact on the house color.
I have more opinions: gray and taupe roofs go well with blues, grays, pale aqua (my favorite), gray-greens and yellow. Brown roofs, and warm taupe roofs, go well with (yellow)green, golden yellow, red, beige, carmel... Of course there are exceptions to every opinion, including mine.
For your house, I would consider gray with black shutters or blue-gray with navy shutters if your roof is not brown. With a brownish roof, for your house, I would consider carmel, or butterscotch with creamy trim and red, dark green or dark blue shutters. Of course I love color, so white wouldn't work for me.
