It’s not artificial, it’s from a real place of need and for many people, has nothing to do with how people approach a dog.
I still think it's an artificial and arbitrary choice.
Certain colour combinations seem to naturally signify "caution" or "danger", like the yellow and black stripes of bees and wasps. But I don't think that solid yellow for "keep away from my dog" is any less arbitrary a choice that the choices of red, amber and green for traffic lights.
And I now realise that I should used "leash" in the thread title, because every time I see it now, I think it's about PbCrO4.
