An artist and innovative art researcher, Don brings aesthetics into the light of day, and into the kitbag of the practising artist, out of the sophistry of semantic philosophy. His speciality is the psycho-aesthetics of colour, and its power to create different scenarios and reveal subtle aspects of character, as does his diagnostic computer program ProMICAD, approved by the UK Government and used in schools, universities and careers agencies. Notably, he introduced game theory into art and design. His researches were sustained over 20 years as Senior Lecturer at Kingston College of Art and Design, and for many years was in charge of Basic Design and art-anddesign dissertations for BA(Hons) and MPhil courses at what is now Kingston University. His research was continued by Roy Osborne at Oxford Brookes University. He is cofounder of both the Colour Reference Library at the Royal College of Art and the National Art Education Archive at Bretton Hall, under the aegis of Leeds University. He is a Fellow of the Royal Society of Arts and an Associate of the Royal College of Art with the Medal of Special Distinction. In 1997 he was awarded the Newton Medal of the Colour Group (Great Britain) for his unique contribution to colour research.
