顏色：黃銅的亮黃
最直接的一層：直接說某樣東西看起來像黃銅。
adjective · C1
Bright gold-yellow, like brass — and, more widely, looking like brass in colour or shine.
黃銅色的
核心畫面
One way to hold this word: hold a piece of brass. It is yellow, it throws light back at you, it is hard under your thumb, and if you knock it the note rings out and carries. Now notice that it is not gold — close, but harder and cheaper. Every use of brassy is one of those four things lent to something else: the yellow shine, the ringing note, the hardness that will not give way, and that small gap between looking like gold and being it.

可以想成手上握著一塊黃銅。它是黃的，而且很會反光。摸起來硬，指甲壓不出痕跡。敲一下，聲音又響又亮，還傳得很遠。再注意一件事：它很像金，但不是金。硬一點，也便宜一點。brassy 的每一種用法，都是把這四樣裡的一樣借出去。可能借顏色，可能借那個響聲，可能借那種不退讓的硬度。也可能借的是「看起來像金，其實不是」的那個差距。From the word’s history
The adjective is simply brass plus -y, the ending that means 'having the quality of'. So the word has never pointed anywhere except back at the metal; everything it describes is being compared to brass.
這個形容詞就是 brass（黃銅）加上 -y。-y 的意思是「帶有某種性質的」。所以這個字從頭到尾都指著同一塊金屬。它形容什麼，就是在說那樣東西「有黃銅的味道」。顏色、聲音、態度，都是這一塊金屬借出去的。
