Since its inception in 1917, the Journal of the Optical Society of America has served as an important forum for research on color vision. This special issue on Color Vision continues that distinguished tradition and profiles present frontiers in both basic and applied research on color vision, including perception and psychophysics, physiology and anatomy, functional imaging, genetics, and color-vision deficiencies.

Most of the articles in this issue are based on presentations at the 2011 Biennial Symposium of the International Colour Vision Society (ICVS) that was held at Buskerud University College in Kongsberg, Norway, in July 2011. Contributions to the conference reflect the diversity of interests of the members of the ICVS, who include physiologists, psychologists, physicists, engineers, geneticists, optometrists, ophthalmologists, and other related professionals with interests in color vision and color-vision deficiencies. To learn more about ICVS and to find information about regular or discounted student membership, visit the website www.icvs.info. We invite you to join us for the 22nd Biennial Symposium, to be held in Winchester, UK, July 14–18, 2013.

The editors of this special issue are grateful to the contributors and referees who made this issue possible. We especially thank the Editor-in-Chief, Dr. Franco Gori, for the opportunity to publish in this special issue and JOSA A staff for their patient and diligent assistance.

2011 Verriest Medal awarded to Dr. Steven K. Shevell

The International Colour Vision Society awarded the 2011 Verriest Medal to Steven K. Shevell. Professor Shevell is the Eliakim Hastings Moore Distinguished Service Professor at The University of Chicago, in Psychology, Ophthalmology & Visual Science, and Computational Neuroscience, and immediate-past Chair of the Integrative Neuroscience Graduate Program. For over 35 years, Professor Shevell has contributed to the vision and particularly the color vision community in breaking new ground in research, training new researchers, and providing service to the community. In his experimental work, he has carefully integrated theoretical and experimental approaches in studies of how early mechanisms and context influence color perception. He has artfully exploited the technique of hue cancellation to study adaptive processes, spatiotemporal constraints, memory, and binocular integration in color perception. Professor Shevell is an OSA, ARVO, and APS Fellow and the editor of OSA’s The Science of Color (2nd edition). In addition, he has served, over the years, on editorial boards of leading journals, review panels of leading granting agencies, and on the boards of major research societies. He is currently a member of the Directors’ Board of the ICVS. His wise and equilibrated advice is sought after in our deliberations and personifies the voice of careful research, integrity, and reason.
