Exercise : match the images with the the appropriate colour idiom

How are you feeling today ? Are you feeling blue or great ? Last week, I wrote a post about some idioms related to colours. Now I propose a quick exercise. Have a look at these images and try to identify the idiom each one of them is referring to. If possible, try to remember the meaning of them. After that, as usual, you can check your answers by having a look at the bottom of the page. Understood ? Let's get to it, then :
1)                                                     2)

3)                                        4)

5)                                             6)

7)                                              8)

Answers :

1) Once in a blue moon = rarely, when pigs fly.
2) Go red in the face / go red as a beetroot / go red as a lobster / go red as a beet / go beet red  = Blush because of an embarrassing situation.
3) To be green with envy = become envious of someone
4) To be someone's blue-eyed boy  = Someone who is prized and favoured over others.
5) To have blue blood = To have royal or aristocratic backgrounds or lineage.
6) To feel blue = To feel sad, down in the dumps, depressed.
7) To paint the town red = To go partying or on a binge alcohol.
8) To have a black heart / to be a black-hearted person = To be cruel, merciless and despicable.

I really hope you've been able to remember most of the idioms from the previous post. I'm off to Salamanca now but next week I will be writing a post about the importance of English to commemorate the European Day of Languages.
Have a nice weekend.
