I would color this picture in a warm and inviting way. I would use a rich brown for the man's coat and hat, as well as for the door and trim of the house. I would use earthy tones for the siding of the house, like a sandy brown, and I would pick a mossy green for the tree's foliage. I would throw in some bright oranges and yellows for the leaves on the ground. The scene would be completed with a bright, yellow-tinted sky and a few fluffy white clouds. The picture would be inviting and cozy, with the man seemingly looking at the house in admiration.
