Principles of colour and appearance measurement. Volume 2, Visual measurement of colour, colour comparison and management /
Colour and appearance perceptions are very complex psychological phenomena. Written by one of the foremost authorities in the field, this major two-volume work addresses the key topics required to understand the issues and manage colour effectively. This volume addresses the visual measurement of co...
