Seeing The World Without Color

Have you ever been curious to know what people who are Color Blind see? How do they distinguish between the large numbers of colors that are out there? Can they tell certain colors? Let your curiosity lead you to Vischeck.

Vischeck offers a web service that simulates the world as seen by color-blind observers, observers at a distance, or users of LCD displays. The integrated vischeck system has been developed by two scientists at Stanford university:

Robert Dougherty PhD

Dr. Dougherty completed his doctoral work in the psychology department of the University of California, Santa Cruz. He worked as a postdoctoral fellow in the department of ophthalmology at the University of British Columbia and the BC's Children's Hospital Visual Neuroscience Lab before moving to Stanford. After a short leave from academics to run a small company, Dr. Dougherty returned to Stanford as a senior research scientist to help form the new Stanford Institute for Reading and Learning (SIRL). He uses functional brain imaging and psychophysics to study visual and auditory processing.

Alex Wade PhD

Dr. Wade completed his doctoral work on retinal imaging at University College London in the Institute of Ophthalmology and Moorfield's eye hospital. He is currently studying the perception of colour and form in the human visual cortex using functional magnetic resonance imaging.

This site is a great resource on Color Blindness, and can be visited by clicking on the following link.
