Picture a bar of iron going into a fire. It darkens, then glows dull red, then orange, and if the fire keeps going it turns a bright, painful white. That white is the top of the scale — you can see the heat rather than feel it. Everything this word does can be traced back to that last colour: white means the highest setting, whether the thing being heated is a piece of metal, a person's anger, or a market.
可以想成一根鐵棒被放進火裡。它先變暗，接著發出暗紅的光，再轉成橙色；火要是繼續燒，它會變成刺眼的白。那個白是這條階梯的最上面一階——熱到你用看的就知道，不必伸手。這個字的每一種用法都能拉回那個顏色：白代表強度開到最大，不管被燒熱的是一塊金屬、一個人的怒氣，還是一個市場。
