I would like some opinions/advice on colour choice for front of house render & roof restoration please.

I am getting a roof restoration done at the same time as rendering the front & back of house, as well as fences painted & can't agree/decide on what sort of colour scheme to use. We know we do NOT want stock standard cream render looking at something perhaps a little darker (have seen Solver Crag Grey & quite like that), but with no eye for detail would appreciate some advise on what colours people would go for including roof/gutters etc. Also, would you do the window shutters as well?
