鸡蛋有红皮、白皮、绿皮，有什么区别？

Peruse the egg section of a grocery store or farmers market, and you'll notice cartons of eggs separated into white and brown, sometimes even green or blue eggs. But once they arrive scrambled on a plate, perhaps, or baked into a cake, it's tough to tell the difference. In fact, what is the difference between eggs with shells of different colors?

去超市或农产品市场仔细观察成箱的鸡蛋，你可能会注意到鸡蛋既有白的，也有褐色的，有时候甚至是绿色或蓝色的。可是变成炒蛋或蛋糕之后，又基本看不出区别了。那么，这些鸡蛋除了蛋壳颜色不一样，还有什么不同呢？

This isn't a flour or rice situation. Brown eggs are not more "natural," and white eggs have not been decolored with bleach. Both varieties occur completely naturally, as do bluish-green chicken eggs. But really, all chicken eggs are the same on the inside. So what causes different egg colors among the same type of bird?

这跟面粉或大米不一样。褐色的鸡蛋不一定更“纯天然”，而白色鸡蛋也不是被漂白了。相反，它们生来就是那样的，包括蓝绿色的鸡蛋也是。但不管蛋壳颜色如何，它们的内在实际上都是一样的。那为什么这些鸡蛋都是母鸡生的，“肤色”却各有不同呢？
