Do you like delicious blueberries? If so, when you eat next time, take a look at them. Are they really blue?
Not really. Take off the skin (表皮). The inside is white. Rub (摩擦) the inside of a blueberry on a piece of white paper. It is reddish - purple. And if you rub the outside of a blueberry, it gets almost black. But the moment you pick one, it does look blue. Why?
①The first way is through "structural colour (结构色)". ②The blueberry makes "structural colour" in its own way. ③When the blueberry is fully grown, it is black. ④But a thin layer of wax (蜡层), on the outside of the blueberry, gives it a blue look.
The second is through plant pigments (色素). The pigments on the blueberry skin take in (吸收) green and yellow light and reflect blue light. That's why blueberries look blue in our eyes. In fact, there aren't any "true blue" in the plants. We can also see the similar features (特点) on the green leaves.
The blueberries' special colour way is cool. It shows nature's magic. More secrets in our nature are waiting for us to discover! Now your bowl of blueberries suddenly looks a lot more interesting!
