A lot of English idioms use colors to describe feelings. Below are just
a few examples.
Jessica was seeing red when her computer suddenly crashed.
When George brought home his expensive car, his neighbor Bill was green with envy.
After Susan’s boyfriend left her, she felt blue and cried all the time.
He was a yellow-bellied cowboy. He always ran away from a fight.
John asked Nancy to marry him. He was
*tickled pink when she said yes.
To see red=very angry
We probably use red to describe anger because people’s faces turn red when they are angry. Imagine you became so angry your eyes became red, too. Then you might begin to “see red.”
I’m not sure why people are green when they are envious, but this is a very common saying.
. To feel blue= sad
You can also “be blue.”
. Yellow bellied= coward, not brave
Belly means stomach. If your belly is yellow, you are not brave. This idiom isn’t used as much nowadays as it was in the past.
. Tickled pink= very happy
When someone is tickled, he feels very excited and happy. Perhaps your skin becomes pink when you feel happy.
