Individual Differences in Color Matching and Appearance
Instructor: Mark Fairchild, Rochester Institute of Technology
Level: Advanced
Duration: 2 hours plus 15 minute break. After the class, adjourn to Zoom to join the instructor and other students in a discussion of the class.
Course Time:
    New York: Friday 13 November, 10:00-12:15
    Paris: Friday 13 November, 16:00-18:15
    Tokyo: Saturday 14 November, 00:00-02:15

Benefits:
The attendee will be able to:

• Explain observed individual differences in color perception.
• Identify the physiological and anatomical differences in the visual system.
• Compute individual color matching functions based on a physiological model.
• Predict differences in chromatic adaptation and their level of importance.
• Define the impact of individual differences on their own color applications.

Intended Audience: scientists and engineers who used colorimetric and color appearance models in their work and are interested in the fundamental components of our human visual system that impact the accuracy, precision, and individual applicability of such systems. Also, anyone who is simply interest in color science should enjoy the course.

Course Description:
Individuals are different, by definition. Individuals typically differ in many anatomical and physiological aspects including the sensitivity and scaling of their sensory systems. This course examines individual differences in color matching functions and how they impact fundamentals of colorimetry (XYZ, CIELAB) as well as individual differences in chromatic adaptation that might be caused by higher-level perceptual mechanics and thus impact color appearance (CIECAM02-type metrics). Anatomical and physiological differences that impact color perception are described along with suggestions for dealing with them in practical color measurement. Specific topics include observer metamerism, categorical color matching functions, observer calibration, statistical models of color matching, uncertainty in adaptation, individual differences in corresponding colors, chromatic adaptation hysteresis, and improving practical adaptation models.
