Sorry I don't understand.
Water by itself does not
cause any damage.

It promotes growth of Fungii.
The fungii cause discoloration.

I have seen rain cause colored spots on my roses. No fungus here.
Just bugs.

Same thing happened to one of my iceburg roses. Its next to several
red
roses including a Mr Lincoln and now it has red spots all over the
flowers.

I think that its partly due to the weak nature of the particular
plant.
Another iceburg in the same bed, which is stronger, is not affected.
