英语里有许多俚语，和颜色有关的如下，地道表达

1, see sth through rose-tinted glasses

带着有色眼镜看待这个世界？NO， rose-tinted 是玫瑰色的，希望的，乐观的意思。

所以 see through rose-tinted glasses 是乐观地对待事物。最近在学习记忆法提高术，看到这个俚语我会想到一个胖胖的乐观派戴着粉红色桃心的眼镜，笑哈哈地张着嘴。OMG, 想忘都忘不了。

例句：She looks happy ever day. She see the world through rose-tinted glasses.

2, give someone the green light

看到green light 就知道是让你一路畅通无阻的绿灯了。所以 give someone the green light 就是给某人绿灯，允许某人做某事的意思。

to give permission for someone to do something or for something to happen:

例句：Can you give me the green light to roll in this school without test.? Absolutely not possible!

3, paint the town red

我是一个粉刷匠，粉刷本领强！我要把这座城刷成红色的海洋！

Paint 意思是“绘画、喷涂”，paint the town red字面意思是是“把城市涂成了红色”。在有些表达中，红色在西方代表愤怒，冲动。不过也有褒义之说。据说 red 的褒义是从远东经波斯传到西方的，在中国文化中红色是喜庆，快乐的意思。所以结合两者，快乐和冲动，就是狂欢作乐的意思。It means to have a good time through visiting nightclubs and bars etc.

paint the town red

英 [peint ðə taun red] 美[pent ði taʊn rɛd]

[词典] 狂欢作乐;

[例句] With so much money, we can really paint the town red.

有这么多钱，我们就能大肆狂欢了。

4, blue / white collared

collar就是衣领的意思。马上就明白 blue / white collared 是蓝领 / 白领了有木有！

例句：Do you want to be a blue or white collared worker? Why don‘t you ask me what kind of career are you pursuing?

5, in black and white

白纸黑字，是是非非都清清楚楚写在了纸上，可不许耍赖哦！

in black and white

英 [in blæk ænd hwait]美[ɪn blæk ənd hwaɪt]

[词典] 白纸黑字;

[例句] He gave me assurance in black and white.

他给了我书面保证。
