About This Book

Heterochromia

This article relates to Dark Water

Print Review

Pearl has one brown eye and one blue eye. Amiel says to her that this means "tu eres de dos mundos. You are of two worlds." Pearl's uncle says it means that she can see fairies and peaceful ghosts.

But what is it exactly?

Heterochromia simply means a difference in coloration and is caused by a relative excess or lack of melanin. The term is sometimes used to describe distinct differences in hair or skin color, but most commonly refers to the coloration of the iris.

Complete heterochromia is when the iris is a different color entirely. Partial heterochromia is, as it sounds, when only a part of the eye is different. Heterochromia is most often an inherited condition, but it can also be the result of mosaicism (two populations of cells with different genotypes) or the result of an injury or disease. Like both Pearl's uncle and Amiel, some people and cultures have credited the two color phenomenon with powers such as having the ability to perform witchcraft, or as having "ghost eyes," which is the gift of seeing both heaven and earth at the same time.

siberian huskyHeterochromia is common in some species of animals - cats, horses and dogs (especially Siberian huskies and various sheep dogs such as Australian shepherd and border collies). It is rare in humans, but Pearl does share this wild-eyed condition with some famous folks: Alexander the Great, Dan Ackroyd, punk rocker Tim McIlrath, Detroit Tigers pitcher Max Scherzer, Jane Seymour, Kate Bosworth, and Kiefer Sutherland, to just name a few.
