Measuring Colour

New edition of the highly regarded ‘Measuring Colour’; updated to include the latest International Commission on Illumination (CIE) standards. This book is intended to provide the reader with the basic facts needed to measure colour. It is a book about principles, rather than a guide to instruments. With the continual advances in technology, instruments are being improved all the time, so that any description of particular colorimeters, spectroradiometers, or spectrophotometers is likely to become out of date very quickly. The principles of measuring colour are not subject to rapid change, and are therefore appropriate for treatment in the more permanent form offered by books. The authors discuss that while colour is the dominant contributor to the appearance of an object or material, the gloss of that material - its ability to reflect light from its surface, the translucency of the material - its ability to partially transmit as well as reflect light, and the surface texture of the material - the variation in appearance due to surface pattern or irregularities, all contribute to its appearance and, although the measurement of these percepts is largely in its infancy, some insight will be given to a framework that will enable suitable measurements to be made. Colour is primarily a perception experienced by the individual. For this reason, the material has been set in the context of the properties of colour vision of the human observer: the first chapter is a review of our current knowledge of colour vision; and the last chapters provide a description of models of colour vision that can be used to extend colour measurement to the field of colour appearance, a detailed description of the model that has been adopted by CIE being included.
