Apart from a few artificially coloured sweets and cakes, and even those are rare. As far as I can see, nothing edible for humans is naturally blue. I can think of examples of food of every other colour, bu8t not blue.
If you are going to claim that mulberries, blueberries etc are purple and not blue then you are going to have to provide some actual reflectance figures to support that. They look blue to me. Many berries are naturally blue.
Blue is probably less common than some other colours because the dispersal agents, birds and mammals, are attracted to the warm colours and so very little fruit will develop cool colours. The only common green foods are plants that are either unripe or vegetative parts. There are some green fruit that are green simply because the never develop any other colour, so it’s a default. Blue however requires a specific pigment be produced, and that is unlikely to happen if nothing is attracted by the fruit
If you claim blueberries are purple, you’ve never actually seen a fresh blueberry. They are definitely blue, ranging from deep royal blue to navy. Some have a purplish tinge, but most are a shade of deep blue. They may turn purple when cooked, but who needs to cook blueberries?
Web graphics are really bad cites for color accuracy. In any case, I have seen fresh ones, and they look more purplish than blue. Certainly not that blue.
Working in a produce store, I can tell you as a matter of fact that while the outside of the blueberrie may well range from blue to purple (I’d say that Q.E.D. and RealityChuck are right). , the inside is NOT blue. It will stain your fingers a nice purplish color.
I’ll back up Athena on that! When we would vacation in Grand Marais (In da UP, eh), there were scads of fresh blueberries growing wild around our campsite. They were a vivid shade of blue, no purple that I could see.
OT; I’d kill for a good pastie, how is it that you cannot get one in Chicago where I can find almost any food 24/7???
There are different varieties of blueberry. The one most people relate to is the big blue one; however, there are smaller, purply ones also that grow wild.
I’ve been wondering now for about three decades how this question even came into being, when there’s a delicious food that is even NAMED for being blue. To me it’s the equivalent of asking, “How come there’s no orange food?”
