So in re-thinking the colors, my new solution is to power wash the outside and cross my fingers that the white is brighter and less dirty. Then all we have to do is paint the shutters and trim black and dark grey and do a nice yellow / avocado door. Sort of an updated farmhouse feel. I think combined with some better landscaping this will look nice and fresh. And of course a pale blue ceiling on the porch adds a touch of cool and a nod to tradition.
