I thought that was what "structural color from wax bloom" meant. It's just the texture of the waxy bloom on the skin of the fruit, not any actual pigment.

Wouldn't that mean we could wipe blueberries with a towel and it would come off on the towel and wouldn't be blue anymore? Maybe I should try and see.

Yes, it works with plums too.

When you freeze them they stop being blue.

That's also a difference between blueberries and bilberries, which are often sold as blueberries. One of them is blue throughout, if I recall, but is more common on Europe vs. USA.

Both are structurally blue on the outside. Blueberries are purple inside (pigments) while bilberries are white inside (structurally, I guess).
