The Colour Group is an interdisciplinary society that draws together those who are concerned with colour in many different disciplines.
Some members come from university research laboratories, some from industry.
So the task of the speaker is an especially difficult one, in that he or she cannot assume an expertise common to all members of the audience. So the Group's Committee asks speakers to take, say, five minutes at the beginning of their talk to introduce systematically the fundamental concepts or facts in their field of expertise. One of the attractive features of The Colour Group is the great age range and loyalty of the members. Some of those who have been attending meetings since the Group was founded in 1941 are now a little hard of hearing. Some young members travel to meetings from Europe and are not native speakers.
