See red

Origin

The vivid phrase "see red" evokes an image of uncontrolled, primal rage, often associated with an enraged bull charging a matador's crimson cape. While scientifically bulls are colorblind and react to the movement of the cape rather than its hue, this popular misconception firmly cemented the phrase in the English lexicon by the early 20th century. It metaphorically captures a moment when anger overwhelms reason, causing one to lash out blindly, as if a red mist has descended, blurring vision and fueling an uncontrollable impulse. The color red, long associated with passion, danger, and anger, makes this phrase a potent shorthand for a sudden eruption of fury.
