Odisseo, water tiles can only have one color. To do what you mentioned (different colors) would require a separate water object, which the game engine would see as a solid as opposed to a liquid. As for the cliffs, we can't get that type of an effect in the TE. So we would have to build it custom, which has been done before in some of XJazz's terrains. However this type of terrain will only be accepted into the SEA.
