Individual Differences in Color Matching Functions: Theory and Practice

Tuesday October 29, 15:45 – 18:15

Convener: Andrew Stockman, University College London

Description 
Individual differences in the spectral sensitivities of their short-, middle- and long-wavelength cones means that we all see colors differently. These differences can be large enough to result in obvious color mismatches in displays and consumer products. Quantifying these differences has obvious advantages for industry. Some products may be optimized to reduce the color mismatches (metamerism failures) seen across different observers, while other products (such as phones or personal displays) may be optimized to individually enhance the colors seen by the end user. In a series of short talks, demonstrations, and panel discussions, this workshop covers:

• Introduction to cone fundamentals.
• The link between cone spectral sensitivities and color matching functions (CMFs).
• Modelling cone spectral sensitivities and CMFs.
• Individual differences in cone spectral sensitivities and CMFs. What causes them. Why do they matter?
• Calculating cone spectral sensitivities and CMFs for individual observers.
• Practical estimation of individual differences (including hardware and software demonstrations).
