Speaker: Prof. Mohamed Sobhy
Colour Vision involves Physics, Physiology, Psychology and Neurology. It is not enough to relate each colour to a specific wavelength as may be implied by studying the visible spectrum. The presentation will explain, through demonstrations and examples, how humans perceive colours.
Lecture at 7.30pm
Prof Sobhy is from The Department of Engineering and Digital Arts, The University of Kent
The presentation will include:
• The artist’s and photographer’s view of colours through the colour wheel, additive and subtractive processes.
• The Trichromatic colour model and its development since Maxwell’s demonstration in 1861
• The results of Guild and Wright which lead to the CIE colour map
• The application of the CIE colour map in colour mixing, lighting and computers
• The Opponent colour theory and its application
• Cone Fundamentals and the more recent results of Stockman and Sharpe
The lecture will be of interest to the following categories of listeners:
• Physicists interested in Calorimetry and Photonics
• Multimedia students and researchers interested in colour in computers, monitors, photography, cinematography and colour spaces.
• Artists interested in colour harmony and colour gamut
• Psychologists and neuroscientists interested in how the brain interprets colour
• Any person interested in how humans perceive colours
