Dang Runah, that is a tough choice. The b&w is typically what I would expect of this shot, but I really like the saturation of the wood in the rafters.
What Ron said, yes. Color is a bit more pleasing to look at for the difference in the wood tones due to sunlight fading low in the structure. The B&W allows us to see the angles and shapes and lines more clearly, but I like seeing the color variation more than being forced to see this as only about "lines".
