One way to hold peachy: a ripe peach in your hand. Soft skin, warm pink-orange colour, sweet smell — nothing sharp about it anywhere. Everything the word does grows out of that one fruit. Point it at a wall or a face and you get the colour; point it at a whole situation and you get the feeling, a life as easy as biting into the fruit. And because that feeling is so unmistakably pleasant, it is perfect for saying when your day is anything but.
From the word’s history
Peachy is simply peach + -y, 'having the quality of a peach', so the fruit is not a metaphor bolted on later — it is what the word is made of.
peachy 就是 peach 加上字尾 -y（帶有…特質的）。所以桃子不是後來才加上的比喻，而是這個字的組成本身。
