Introduction to colour science
This chapter is an introduction to the fundamentals of colour description, measurement, evaluation and appearance. Knowledge of theories and current practices related to these topics is paramount in comprehending how colour is recorded, reproduced and managed in imaging media, subjects that will be introduced in later chapters. Colour is evaluated in different ways. Physicists describe variations in the intensities of wavelengths of visible radiation. Colorimetrists describe the amounts of reference primaries which, when additively mixed, match a particular reference light. Sensory scientists describe an ...
