Young Red Haired Girl Portrait

A common belief about redheads is that they have fiery tempers and sharp tongues. In Anne of Green Gables, a character says of Anne Shirley, the redheaded heroine, that "her temper matches her hair", while in The Catcher in the Rye, Holden Caulfield remarks that "People with red hair are supposed to get mad very easily, but Allie (his dead brother) never did, and he had very red hair."
During the early stages of modern medicine, red hair was thought to be a sign of a sanguine temperament. In the Indian medicinal practice of Ayurveda, redheads are seen as most likely to have a Pitta temperament.
Another belief is that redheads are highly sexed; for example, Jonathan Swift satirizes redhead stereotypes in part four of Gulliver's Travels, "A Voyage to the Country of the Houyhnhnms," when he writes that: "It is observed that the red-haired of both sexes are more libidinous and mischievous than the rest, whom yet they much exceed in strength and activity." Swift goes on to write that: "...neither was the hair of this brute (a Yahoo) of a red color (which might have been some excuse for an appetite a little irregular) but black as a sloe..." In the novel and film Red-Headed Woman, the titular protagonist is a sexually aggressive home-wrecker who frequently throws violent temper tantrums.
