Why do you see red when angry?

Seeing red when angry is a common expression linked to the physiological response of the body to strong emotions. When a person becomes angry, the brain releases stress hormones, such as adrenaline, which can increase heart rate and blood flow, potentially leading to a flushed face. This heightened state of arousal can also affect perception, making colors seem more vivid, particularly red, which is often associated with danger and heightened emotion.
