Exterior Colour Schemes - Modern Greys

I'm struggling to pick an exterior colour scheme that I am happy with.

We have a Shale Grey roof and roller door
We have surfmist windows
The house is contemporary design

So far I have only experimented with colourbond colours as a colour for the cladding.
I dont mind Windspray but Im worried with all the other greys I have used so far it will look like a battleship.
If you have any ideas or even pics of your own house with a grey scheme please pass it on.
I have also tried Dune but I think it might clash with the shale grey roller door.



I'd upload a few pics if only I could work out how...

Regards
Dave

We have just picked our colours a shale grey roof with a feature render solver charcoal and main render solver southwards all tones of grey hoping it will look good
