bilious
This term carries a strong association with sickness and unpleasantness, whether physical or emotional. When describing a person's temperament, it suggests a chronic, simmering irritability rather than a sudden burst of anger, often implying a personality that is naturally sour or caustic.
In a visual or physical sense, the word evokes a visceral reaction of disgust. A bilious color is not merely green, but a specific, sickly hue that mimics the appearance of bile, often used to describe environments or clothing that feel oppressive or nauseating.
