Hey windowsRExp, I'm not fully sure of my answer but... I believe that when water soaks into materials, it increases the density. This can lead to a change in color. However, I do not think that everything gets darker when water is put on it. For example, paint turns into a lighter shade when in contact with water. I hope I helped!
