INTRODUCTION

It is well known that the subject of colour has an impact on a range of disciplines. Colour has been studied in depth for many centuries, and as well as contributing to theoretical and scientific knowledge, there have been significant developments in applied colour research, which has many implications for the wider socio-economic community. At the 7th Convention of Colorimetry in Parma, on the 1st October 2004, the "Gruppo del Colore" was established. The objective was to encourage multi and interdisciplinary collaboration and networking that addresses problems and issues on colour and illumination for professionals and scientists currently working in Italy.
