It will be painted. Difficult to tell what was used originally. The house is over 100 years old, and the wood has gone very gray - at least where I was able to flake off some paint. It may have been a cedar or fir, the softness would indicate that. I doubt I would find suitable fir to replicate what was most likely old growth timber when it was logged a century ago.
At that age it is also very likely bald cypress. Given that you are in PA, it is far more likely cypress than cedar. Fur would not last that long. Cypress will turn gray with age.
