> What color is stone after several centuries of soot?
In all seriousness, we don't know for sure. Since the building is made of brownish stone, and soot is black, I would expect a dark brown or gray color. Some stone is even green because of algae. Stone is very seldom blue.
For the sake of this exercise, the goal is not so much to get an accurate stone color, as to use the hue clock to detect the blue cast in the shadows, and remove it by moving the end points of the blue and green curves around.
