This is part 3 of the series of posts on idiomatic expressions using colours. Previously, we had a look at some red and green idioms. Today we’ll be looking at the most common expressions using the word blue.
Let’s start with feel blue. Chances are you’re already familiar with this one as it’s used a lot. Blue in this informal expression means depressed, or sad and hopeless.
She’s been feeling blue ever since her boyfriend dumped her.
Another informal expression with blue is once in a blue moon and it means very rarely.
Lucy and I were inseparable at university but now that she’s moved abroad and found new friends there she emails me only once in a blue moon, usually when she needs something from me.
The next one is out of the blue meaning unexpectedly.
I was enjoying the sunshine in the back yard when, out of the blue, I smelt smoke and realised the house next door was on fire.
All humans have red blood, though in the past those coming from a noble family were believed to have blue blood in their veins making them very special and unlike ordinary people.
Science has long disproved this theory but the idea survives as a metaphor – we still use the noun blue blood to refer to aristocrats.
Her impeccable manners make people think she’s a blue blood, though in reality she comes from a working class family.
The next idioms originates from the film ‘The Matrix’ where in one of the scenes a choice has to be made between a red pill, which opens your eyes to what the world is really like, and a blue pill, which keeps you blissfully ignorant about it. So, the blue pill is used to mean beliefs that make you feel safe and happy but stop you from seeing things for what they are.
Many people choose the blue pill as it allows them to live a worry-free life.
And the last one for today, a very expressive one I think. To talk till/until you’re blue in the face means to say something a lot but to no effect.
You can tell him to stop drinking until you’re blue in the face but he won’t listen.
That’s it for today. Next time we’ll learn a few commonly used white idioms.
