Jack,

Your link isn't working. As someone else suggested get a bunch of pint
cans in various colors. Paint the back of the house near the ground, near
the trim with these samples. Invite your friends over for a cook out and get
their opinions and votes. Then ignore all of that and paint it to please
yourself. This Winter go to the library and flip through the house
painting/home decor books.

Good luck,
Dave M.
