Rather than try to match the green and tan paint, I chose a more "Northwest" look by using high quality fir 4X4's for the frame, and finishing then with a clear, nearly invisible linseed oil.
The windows and doors are all reclaimed. The old white paint on the windows adds to the charm, and with the wood, it isn't too stark of a contrast with the house.
For Ventilation, both windows in the front open outward, and the two side windows are hinged on the bottom with a catch on the top so they can let the warm air out on a hot day.
