Is the first photo showing the current view of your home with the dark green siding? Please post another photo of the home including the out buildings.

Use the same siding color as the house.

Here's an additional photo of the buildings.  The cottage and outbuildings are on a long, narrow parcel so I don't have a photo including all of them.

I thought about using the same color as the cottage siding, however, I'm not sure if I want all the same color for the four outbuildings.  I'm afraid that may be a lot of green!

I would use same as house, so they all look cohesive.
