Meaning
To become suddenly and extremely angry. The image is of rage so intense that it floods one's vision or judgement; the expression captures the flashpoint at which anger takes over, rather than a slow-burning grudge. Informal but widely understood in both British and American usage. Informal; conveys sudden, flashing anger rather than mild irritation or calculated resentment. Regional use: General English (originally American).
Origin
Etymonline records 'to see red', meaning to get angry, as an American English expression attested by 1898. It belongs to a much older symbolism: English had linked redness with powerful emotion since about 1200 (Etymonline dates being red in the face from strong feeling to that era), and red remains the colour most associated with anger, hatred and aggression. A popular explanation ties the idiom to bullfighting, on the model of a bull charging a red cape, but this does not survive scrutiny: bulls, like many mammals, have dichromatic vision and cannot distinguish red; they charge at the cape's movement, not its colour. No standard etymological reference credits bullfighting as the source. The documented history points instead to the long red-and-rage imagery; the precise mechanism sometimes described, a red haze before the eyes, is conventional paraphrase rather than a matter of record.
