Contemporary axioms for colour reproduction

Abstract

Colour is a complex subject that is inherently multi-disciplinary or trans-disciplinary. This can lead to misunderstandings in the way that the subject is taught. This paper is concerned with common misunderstandings of colour science, in the context of colour reproduction, that are widespread in social media but which can even be found in university-level textbooks. The misunderstandings are represented by four axioms that would need to be true to support the misunderstandings; these are critically evaluated using data (such as colour measurements) where possible or by reference to contemporary theory. None of the four axioms can be supported. Four new axioms are articulated that are supported by empirical evidence. It is suggested that these four axioms could form the basis of teaching material for colour reproduction in a 21^st century curriculum.
