We are installing a fibreglass deck (grey floors with white glass railing) and enclosing the bottom to create a shed. We can pick any siding colour for the shed enclosure including grey, blue like the home or white. Which do you think would go better? Should the shed match the siding of the home or should it match the deck floor colour? The second photo right sample is the fibreglass floor colour we chose. I also included a cropped photo of a similar fibreglass deck with grey siding under against the back of our home.
