The measurement of colour is important in many commercial operations and professions, such as bleaching and colouration of textiles, applications of paints, dentistry and colouration of food products. This book will discuss colour measurement theories, the latest technological and scientific developments of measuring colour and the applications of colour measurement.Part one reviews the underlying theories, principles and methods of how to measure colour. It includes topics such as expressing colours numerically, camera based colour measurement, colour shade sorting and determining and improving the accuracy of colour measurement. Part two presents a selection of industrial applications illustrating the use of colour measurement in textiles, paint, teeth, hair and food.With its international range of contributors, Colour measurement: Principles, advances and industrial applications is beneficial to a variety of readers such as colour technologists, colour quality inspectors, product developers, dentists, cosmetologists and anyone who uses colour in their work. It will also be a valuable reference for academics and students studying design, fashion or colour related subjects.
