Preface

Colorimetry is the science of quantitatively defining, measuring, and communicating a colour of any solid, liquid, or semisolid materials, instead of subjectively describing it, for producing the same colour assured by instrumental testing.

Colour is also one of the most sensitive factors determining the psychological and physical buying decisions of consumers. Hence colour mixing and matching to obtain a desirable shade of solid or liquid products is essential. Initial simple colorimetric measurements have been replaced by spectrophotometric (both absorption spectrophotometry and reflectance spectrophotometry) analysis of colours and updated with digital image analysis of colours in different sectors. Moreover, for more commercial exploitation, every industry understands the importance of colour measurement, communications, and precision matching of colours. As such, this book presents a comprehensive overview of colorimetry. It includes the following ten chapters:

Chapter 1: "Colorimetric Evaluations and Characterization of Natural and Synthetic Dyes/Pigments and Dyed Textiles and Related Products"

Chapter 2: "UV-Visible Spectroscopy for Colorimetric Applications"

Chapter 3: "Reflectance Spectra Analysis Algorithms for the Characterization of Deposits and Condensed Traces on Surfaces"

Chapter 4:"Spectroscopy and Spectrophotometry: Principles and Applications for Colorimetric and Related Other Analysis"

Chapter 5: "Basic Principles of Colour Measurement and Colour Matching of Textiles and Apparels"

Chapter 6: "Colorimetric Measurement and Functional Analysis of Selective Natural Colorants Applicable for Food and Textile Products"

Chapter 7: "A Digital Image-Based Colorimetric Technique Use for Quantification of Green Active Pharmaceuticals Obtained from Natural Sources"

Chapter 8: "Colorimetry in Nuclear Fusion Research"

Chapter 9: "Evaluation of Camouflage Coloration of Polyamide-6,6 Fabric by Comparing Simultaneous Spectrum in Visible and Near-Infrared Region for Defense Applications"

This book presents many scientific case studies on practical guidelines as well as difficulties and solutions for colorimetric analysis in the textile, pharmaceutical, paint, food, defence, nuclear fusion, and other relevant industries. It is a useful resource for dyers, colourists, scientists, researchers, and students engaged in colour analysis, colour mixing, and colour matching.

As editor of this book, I wish to acknowledge the constant support of all the administrative executives, author service managers, and the editorial and production team at IntechOpen, without whom this book project would not have been possible. I am also thankful to the contributing authors for their excellent chapters.
