I think a green or blue. Green will suite the palette of gold tone stone and blend nicely with the surroundings and have a sense of calm. If you want it to be more bold and stand out, then a blue would be a complement to the gold stone and they will both become a stronger more exciting element together.

The actual paint color used for the shutters on this house is Sherwin Williams #3524. Thank you for the great question and for taking a look at our photos.
