In regards to the color of the rockwork & Hogwarts itself, my friend & I were discussing that last night when I showed him that pic. He asked if it looked "grayer" than Orlando. It really does look grayer, however, I reassured him it was just a trick of the light. I pulled up a few pics of Hogwarts Japan that show the castle/rockwork color is brown, but can also appear to be gray due to being washed out from the bright sunlight.
