Why the world is (not) gray: the emergent perception of color

a lecture/demonstration by John Siegfried, Ph.D., Professor of Physiological Optics and Psychology, Pennsylvania College of Optometry

Tuesday, January 4, 12 noon
The Little Theatre (directly adjacent to the Art Gallery), Spruance Art Center
Free and open to the public.

Dr. John Siegfried is a distinguished member of the faculty of the Pennsylvania College of Optometry, Elkins Park, where he has been a Professor since 1980. In addition to affiliations and positions with institutions across the nation, he is author of over one hundred papers and presentations on the subject of the electrophysiology of human vision and its diagnostic clinical applications. Applying his experience with diagnostic tests in color vision, visual thresholds, and contrast sensitivity, he will address the following topics in his illustrated lecture:

  • Why there is no "color" in the external environment ­ only electromagnetic energy of different wavelengths and intensities reflected by surfaces.
  • Why there is no "image" on the retina of the eye, if by "image" we mean form, color, contrast, and motion.
  • How the perception of color is created by visual processing in the retina and visual cortex of the brain; and why does "red" look "red", anyway?
  • How color appearance can be affected by adjacent chromatic stimuli.
  • How color processing can go wrong in inherited and acquired color deficits.
