My house, built in 2003, has purple feature walls in the dining room and 2 bedrooms and green feature walls in 1 bedroom and 2 living areas. That was the fashion then. Recently I decided it's time for an update as the feature walls seem to be absorbing all the light and making the house very dark. So far I've undercoated 2 of the feature walls and what a difference it makes! The rooms are much lighter and now I have to decide on whether to add a lighter colour as feature walls or paint them the same colour as the rest of the room.

Taubmans chilly water (more green) or misty rain (more blue). i'm sure there was a design dilemma post from a while back that gave the Aussie paint answer to this question. Hopefully someone who knows will see this and link it.

Cream always looks good with green, maintain the same green for windows & door. Having said that you can choose any colour by repainting the gutters & fascia etc. Get lots of colour swatches & hold them up to the roof (from a distance) to see what looks best to you. Then get some sample pots & paint so you get the proper effect of the end result. Look around at other painted homes & magazines etc, to get an idea of what you really like.

Black sounds perfect.
