Colour Science in the Future

Abstracts

The Challenge of our Known Unknowns
Robert W. G. Hunt
Color Consultant, Salisbury and The University of Leeds

Although much is known about colour vision and imaging, there are still important gaps in our knowledge,
and the possible impact of these gaps needs addressing. Such topics include the following:
Why are colour-matching functions based on matches on white, and on matches on spectral colours,
different, and what are the implications of this on colour technology and imaging?
Why does sharpening colour-matching functions lead to better chromatic adaptation transforms?
Why do the unique hues occur where they do in colour space?
How are the rods inhibited at high levels of illumination?
Why do bluer whites look whiter than neutral whites of the same reflectance, and why is this also
true of blacks?
How can predicting the colour rendering properties of white LEDs be improved?
How can the use of true luminance signals be achieved?
How can displays using a luminance signal be engineered?

CIE Colour and Vision
Michael R Pointer
University of Leeds, Leeds

The Terms of Reference of CIE Division 1 Vision and Colour are:
To study visual responses to light and to establish standards of response functions, models and
procedures of specification relevant to photometry, colorimetry, colour rendering, visual
performance and visual assessment of light and lighting.
The Division currently has 28 active Technical Committees, five of which were established at
the meeting held in Budapest, Hungary in June 2009. In addition, there are nine reporters who
are investigating new areas of work.
This presentation will give an overview of the work in progress with some views as to the likely
achievements in the (near) future!
