That's interesting theory 😌 Because I thought the color blue in nature is so unnatural that it should not even attract people's attention. But that's not the case, as we know it.
Every time I think of blackthorn, I perceive it as unnatural. But then I think of the other blue fruit that I myself eat. For example - ordinary plums. I don't find them unnatural at all when I eat them 😁
