The English expression “seeing red” means becoming very angry or furious. When someone is “seeing red,” they are so angry that they may temporarily lose their patience or find it difficult to think calmly.
Definition
Seeing red = to become extremely angry or enraged.
Example:
- When I discovered that someone had stolen my bicycle, I was seeing red.
This expression is very common in both spoken and written English. It describes a strong emotional reaction rather than ordinary annoyance.
Where Does the Expression Come From?
The origin of “seeing red” is not completely certain, but there are a few popular theories.
One theory comes from the color red itself. In many cultures, red is associated with:
- Anger
- Danger
- Violence
- Strong emotions
When people become very angry, their faces often turn red because of increased blood flow. Because of this physical reaction, the color red became linked with anger.
Another theory comes from bullfighting. Many people believe that bulls become angry when they see the matador’s red cape. Although scientists now know that bulls are color-blind to red and react to the movement of the cape rather than its color, the image of an angry bull charging at a red cloth helped popularize the expression.
Regardless of its exact origin, “seeing red” has meant extreme anger for more than a century.
How Strong Is the Expression?
“Seeing red” describes stronger emotions than:
- being annoyed
- being irritated
- being upset
It is similar to:
- being furious
- being enraged
- being livid
- being mad as hell
Compare these sentences:
- I was annoyed when the train was late.
- I was seeing red when someone damaged my car and drove away.
The second sentence shows a much stronger emotional reaction.

意味
seeing red = 非常に怒る、激怒する
例文：
- When I discovered that someone had stolen my bicycle, I was seeing red.
→ 誰かに自転車を盗まれたことを知ったとき、私は激怒した。
この表現は、日常会話でも文章でもよく使われます。単に「少し腹が立つ」という意味ではなく、非常に強い怒りを表します。
この表現の由来
「seeing red」の正確な起源ははっきりしていませんが、いくつかの有力な説があります。
1. 赤色と怒りの関係
多くの文化では、**赤色（red）**は次のようなものを象徴します。

- 強い感情
人は怒ると血流が増え、顔が赤くなることがあります。そのため、昔から「赤」は怒りの色として結び付けられてきました。
2. 闘牛のイメージ
もう一つの説は闘牛に由来するというものです。多くの人は、雄牛が赤い布を見て怒ると思っています。しかし、実際には牛は赤色そのものに反応するのではなく、布の動きに反応します。
それでも、「赤い布を見て突進する怒った牛」のイメージが広まり、「seeing red」という表現の普及に影響を与えたと考えられています。
