Why do they dye some pistachio nuts red?

Answer 1

Originally the dye was applied by importers to hide stains on the shells caused when the nuts were picked by hand. However most pistachios are now picked by machine and the shells remain unstained, making dyeing unnecessary (except that some consumers have been led to expect colored pistachios).

And the sky is blue because of the "Rayleigh Effect". While light rays of long length pass through the atmosphere easily, the short (blue) waves are absorbed and scattered by the atmosphere, producing a blue tint in the sky. If you notice on pictures of the moon, the sky is black even during the day. That is because there is no atmosphere on the moon to scatter the light.

There ya go, two answers for the price of one.

Red pistachio nuts are not as common as they were in years past. The reason is that most pistachios are now picked by machine.
