Can’t a beach just be beautiful on its own, without people painting natural objects in artificial colors? The paint is probably toxic, and many fish & invertebrates feed off stones. I hate to think what kind of precedent this might set. It’s no wonder our planet is in such trouble when people think it’s great to leave garish lights on all year long and go around painting beautiful stones with chemical coatings. The idea that people (children included) can’t enjoy things in their natural state is just wrong. Leave it.
