粉色属暖色调，蓝色属冷色调，明亮的粉色和沉静的蓝色恰是一组对比色。而由pink构成的习惯用语的含义和由blue发展成的习惯用语的含义也恰恰相反。Pink用语表达的是喜气洋洋的良好感觉，而blue用语比喻低落忧郁的情绪。

1 feel in the pink

这个短语的出典可能是健康人的脸颊往往是红扑扑的，而脸色苍白却是虚弱无力的迹象，所以人们用in the pink来表示in good health 健康有力。

例句：Today I sure feel in the pink! I had a good night's sleep, a walk in the fresh air this morning, a good breakfast, and I feel like I can get a whole lot accomplished today!.

今天我感觉精力充沛！我昨晚睡了个好觉，一早又在清晨的新鲜空气里散了步，好好吃了顿早餐，所以我觉得自己今天能完成好多工作。

2 tickled pink

Tickled 除了大家都知道的"被弄得发痒或者咯咯笑"的意思外，也有"给逗得高兴"的意思。Tickled pink的意思就是：Very pleased; delighted 感到万分高兴。

例句：I'm tickled pink to hear that Bob's asked Susan to marry him. They're both my good friends and I've always thought they were made for each other. I know they'll be very happy together.

听到Bob向Susan求婚的消息我感到万分高兴。他俩都是我的好朋友，而且我一向觉得他们是天生的一对。我知道他们在一起会非常美满。

3 feel blue

人的情绪时起时伏，feel blue 的意思是：be depressed or sad 心情闷闷不乐，情绪郁郁寡欢。

例句：I woke up feeling blue and I've been feeling blue all day. I don't know why: everything's okay with me. Maybe it's this terrible weather--cold and rainy for five whole days in a row!

我一早醒来就心情不好，接着一整天都闷闷不乐。我都不知道是什么缘故，因为我的一切情况都正常。也许是由于这讨厌的气候；整整一连五天都是没完没了的阴雨天气！

4 sing the blues ; cry the blues

有一种情调感伤的美国黑人歌曲，就称为the blues蓝调，但习惯用语sing the blues或者cry the blues 不能按照字面意思解释为吟唱蓝调或者大唱蓝调，而是to complain 诉苦的意思。

例句：I just spent two hours listening to Bill sing the blues about his girl friend leaving him for some other guy. I feel sorry for him but he ought to forget it: after all, it happened two years ago.

他刚花了整整两小时听Bill诉说女朋友怎么甩掉他跟了别人的伤心事。他当然为 Bill 感到难过，但是他觉得Bill该把这事丢在脑后了，因为这毕竟是两年前的往事了。

Sing the blues和cry the blues意思都是诉苦，一吐胸中的愁闷，而feel blue和它们不同的是烦恼压抑在胸中。
