What Exactly Are Color Idioms?
Color idioms are super common English expressions that use colors to describe feelings, situations, or ideas in a fun, non-literal way.
They are phrases that add special meaning simply by adding colors to sentences.
A classic example would be:
“I’m feeling blue”, which basically translates to “I’m feeling sad”.
Doesn’t that remind you of the Disney movie ‘Inside Out’? Well, that’s part of what color idioms can be: an association of colors to specific things.
For example, when we think of…
- Blue: sadness.
- Red: anger
- Green: jealousy.
- Yellow: happiness
