What colour are you associated with? : colour idioms II

Hello there,

Some time ago, in September, I wrote a post about some colour idioms, and I promised I would soon reprise it with brand new idioms. I also include a funny exercise. Well, now that I'm seeing colours with my students of Básico 1, it's the perfect opportunity, so let's get started :

Brown is associated with security and stability because it's the colour of the earth. It is also associated to material possessions. However, this is not reflected in the idioms. 

1. Brown off : When you brown someone off, you irritate and infuriate them,e.g. 'Madrid's traffic jam browns me off every day.' 

2. Brown-nose : Try to please someone in a way that other people may find odd or disagreeable. 'He always brown-noses new managers. That's in his nature.'

Yellow is the colour of hope, sunshine and happiness, but, as you can see, it has some negative idioms, such as number 1. 
1. To be yellow : To be a coward. 'If you don't want to come with us to the haunted house is because you're yellow.'

2. a golden opportunity : A very good opportunity. A scholarship to the United States is a golden opportunity.

Pink represents compassion, empathy and love, what is is conveyed by the second idiom. 

1. See pink elephants : To be so drunk, to the point of having hallucinations. 'When I started to see pink elephants, I knew that I was really drunk.'

2. Tickled pink : Very much pleased. 'I was tickled pink when I received the invitation to her wedding party.'

Grey represents the in-betweeners, something formal or sophisticated. 
1. A grey area / a gray area : A situation where there are no clear rules,e.g.  'I don't know if that activity is illegal. I think there is a great area.'

White is often associated to purity and transparency and this is somehow reflected in the idioms.

1. It's not black or white : We can't classify all problems in a category. There are grey areas, for example, 'not all immigrants are criminals and not all citizens are innocent people. Everything isn't just black or white. There are grey areas.'

2. Show the white flag : Give up, surrender, for instance, 'the team decided to show the white flag when they lost their best player.'

3. A white lie : A very small lie, a fib. 'He didn't want to spare his feelings so he told her a white lie and said he had enjoyed her presentation.'

4. To be as white as a sheet : To be very pale. 'Oh man, what's the matter ? You're as white as a sheet ! Go home and rest. 

Well, I hope you have a colourful weekend and that you have learnt a lot about colour idioms. See you next week with an important event for the US, Thanksgiving. Have a nice weekend.
