The topic of colour vision is one that integrates research from psychology, neuroscience, biology, opthalmology, 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 thebrain 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?John Mollon, Joel Pokorny, and Ken Knoblauch are leading authorities on the perception of colour. Together they have brought together a distinguished list of contributors to provide an interdisciplinary review of the field. An historical introduction marks the bicentennial of Thomas Young'strichromatic theory and provides useful background for the newcomer to the topic of colour vision. Carefully edited and indexed, this book is aimed at students and researchers in the visual sciences, in perceptual psychology, and in sensory neuroscience. It will be a definitive text on colourperception for some years to come.
