Architects Have Great Tools - Exterior Color Studies

At Ron Brenner Architects we have been working on a series of color studies for a client of ours.
I have included a number of the studies below.  The client has selected a medium gray for the base body color; however I also did a couple of non-gray variations.  The black roof is a given on all schemes.  Which one would you choose?

scheme 1 - all white horizontal clapboard siding

scheme 2 - gray board and batten siding, rusty corrugated metal inside porch and in 'link" area

scheme 3 - dark gray board and batten body color with white clapboard inside the porch and in link area

scheme 4 - gray board and batten body color with dark plum inside the porch and in the link area

scheme 5 - gray board and batten body color with white clapboard inside the porch and in the link area

scheme 6 - gray board and batten body color with dark gray shakes inside the porch and  in the link area

scheme 7 - gray board and batten body color with white shakes inside the porch and in the link area
