The 1986 interim meeting of the AIC (Association Internationale de la Couleur, the International Colour Association) was held at Ryerson Polytechnical Institute in Toronto, Ontario, Canada, on July 1920, 1986. The meeting was organized on behalf of the Canadian Society for Colour by a committee chaired by Peter Kaiser. Its theme was Colour in Computer Generated Displays. All the papers addressed, in one way or another, problems or opportunities inherent in using colour for computer generated imagery. This theme was designed to appeal to four different communities who use coloured imagery:

The AIC interim meeting followed the joint annual meeting of the Canadian Society for Colour and the Inter-Society Color Council, which took place in the three days immediately preceding the AIC meeting. Thus, the first of these groups was unusually well represented.

There were about 120 attendees for the two days of papers at the 1986 AIC interim meeting, which were divided into four sessions. The first session, ``Using Colour for Information Display,'' began with an invited paper by Joann Taylor and Gerry Murch which reviewed many effects that arise when colour is used to display information.

The second session, ``Colour Standardization,'' began with an invited paper by Paul Tannenbaum which reviewed the history of colorimetric calibration of colour CRT's. There was a second invited paper by Paula Alessi describing the standardizing committees working in the area of display colorimetry and inviting participation. Two other highlights of this session were a paper by Brian Wandell which examined the colorimetric information in the output of colour camera data and a paper by Gary Meyer and Don Greenberg describing how colour is used in the Program of Computer Graphics at Cornell University.

The third session, ``Monitors and Vision,'' began with an invited talk by Don MacLeod showing some interesting effects and illusions that can be produced and controlled using computer-generated colour displays. There was also an entertaining paper by Stuart Anstis, with mime by Jeff Mulligan, describing the use of colour displays for diagnosing colour blindness in infants.

Finally, the fourth session, ``Hardcopy and Other Media,'' began with an invited talk on the state of the art in electronic colour printers by Gary Starkweather. Also in this session was a paper by Maureen Stone describing tools for graphic design at Xerox PARC. All the contributed papers and extended abstracts of the invited papers were published in a special issue of Color Research and Application, which was distributed to participants at the conference. Of particular interest in this issue are the coloured illustrations. They were printed from offset screens prepared at Xerox PARC by Maureen Stone, John Beatty and William Cowan from images supplied in digital form by the authors. The printed Meyer and Greenberg images suggest that offset printing is capable of producing very satisfying reproductions of synthesized imagery.

Additional copies of the proceedings are available from the publisher of Color Research and Application: Shirley Hochberg, John Wiley and Sons, 605 Third Avenue, New York, N.Y. 10158 at $15.50 each.

A primary aim of this meeting was to mix together researchers from different disciplines who share an interest in colour. The participants, who came from three continents and from a wide variety of research areas, had an opportunity to mingle at a wine and cheese reception hosted at Oakham House on the Ryerson campus. Additionally, Toronto offered June weather which was ideal for walking to the many restaurants and cafes in the downtown area. It will be of benefit to the whole colour and graphics community if the cross-disciplinary contacts made at the meeting continue and mature in the years to come. For those who are less patient, the next interim meeting of the AIC will be the Wyszecki and Stiles Memorial Symposium on Color Vision Models. It will be held in Florence, Italy, June 1013, 1987, sponsored jointly by the AIC and the Commission Internationale de l'Eclairage (CIE).
