GO DEEPER

More ways to understand and use it

When to use it

Use this lively, conversational expression to describe a strong angry reaction. It reports a feeling rather than justifying aggressive behaviour.

More examples in context

  • Repeatedly being interrupted makes her see red.
  • He was seeing red, so he waited before replying to the message.

Usage note

The past tense is “saw red”. Do not add “the” before “red”. It does not require seeing an actual red object, and it is stronger than feeling mildly annoyed.

A short conversation

A: Why did you wait until this morning to respond?
B: I saw red when I read the message and wanted time to calm down.
A: That probably helped you choose your words.
