Normal and Defective Colour Vision

Abstract

Abstract The topic of colour vision is one that integrates research from psychology, neuroscience, biology, ophthalmology, physics, and genetics. How do we make sense of colour in the world, and how has such an ability evolved in humans? How are colours discriminated by the retina, and how does the brain interpret chromatic information? How can our genes influence the way in which we perceive colours? Why do some people have problems perceiving colours, and what occupational difficulties may they face? In what ways is colour vision altered by disease or toxins? The editors of this book have brought together a list of contributors to provide an interdisciplinary review on the perception of colour. An historical introduction marks the bicentennial of Thomas Young's trichromatic theory and provides a background to the topic of colour vision.
