“I read this morning that blueberries aren’t blue,” stated Rachel, and Chris stated: “Get out of here. Get out of town.” “I know, right? It’s a trick of the light.”
Reading out what she had learn the day earlier than, Rachel defined that evaluation discovered the seemingly blue color was created by a “colourless, two micron-thick wax layer” which covers the berry.

Scientists on the University of Bristol made a cool discover about blueberries. They took the wax off, made it into crystals on paper and discovered it shines blue and ultraviolet mild, however we will not see ultraviolet, so they only look blue to us.
Rachel stated: “It’s thought the fruit has evolved to look like this, to show off this blue-ish colour, to entice frugivores such as birds. The underlying pigment is more red-ish, but this is a trick also.
“It’s the identical kind of trick that hummingbirds have of their feathers, which apparently aren’t really blue both.”
