Color for porch on new home

Alright guys I have a question. I'm in the process of building a home on a river and need some input. The house is on column stilts which are concrete cinder blocks that will not be painted or stained. The hardie board siding is an iron gray with white trimmings. We have a truss on our porch looking towards the river that will be a dark stained wood as well as our double doors coming onto the porch. We are trying to decide whether to stain the porch railing and stairs a dark wood the same as all the others I listed or paint it white. It is a picket fence type porch railing. Any help would be great
