CIE Division 1 and ISCC jointly organized a symposium to celebrate the 75th anniversary of the CIE 1931 Standard Colorimetric Observer, to discuss the many advances that have been made since its introduction, to understand the current state of colorimetry and colour appearance, and to provide guidance on directions for future work.
The meeting was divided into seven main sessions:

  • Standard Observer
  • Colour Matching Functions
  • Instruments and Standards
  • Temporal and Spatial Issues
  • Application of the Standard Observer
  • Colour Appearance
  • Colour Differences
  • Colour Management
  • Discussion

and included a Poster Session.

A general theme throughout the discussion, that summarized the hot topics of the symposium, was the need for more comprehensive colour appearance and colour difference models. The current models take into account only a relatively small number of factors that can affect the appearance of objects and images. It was recommended that models be developed that include the effect of spatial and temporal factors, that are applicable to all levels of illumination from photopic to scotopic, and that take into account both normal variations in visual functions and changes in visual functions with aging. A second theme was the assessment of visual appearance and visual differences, or more specifically, the measurement of other attributes of surfaces such as gloss, translucency and texture.

The Proceedings contains the full text of all the presented 27 papers and 5 posters.

The publication consists of 200 pages with 158 figures and 22 tables. A CD-ROM with all papers in a searchable form is included.
