From David Hume’s famous puzzle about "the missing shade of blue," to current research into the science of colour, the topic of colour is an incredibly fertile region of study and debate, cutting across philosophy of mind, epistemology, metaphysics, and aesthetics, as well as psychology.Debates about the nature of our experience of colour and the nature of colour itself are central to contemporary discussion and argument in philosophy of mind and psychology, and philosophy of perception. This outstanding Handbook contains 29 specially commissioned contributions by leading philosophers and examines the most important aspects of philosophy of colour.It is organized into six parts: The Importance of Colour to PhilosophyThe Science and Spaces of ColourColour PhenomenaColour OntologyColour Experience and EpistemologyLanguage, Categories, and Thought. The Routledge Handbook of Philosophy of Colour is essential reading for students and researchers in philosophy of mind and psychology, epistemology, metaphysics, and aesthetics, as well as for those interested in conceptual issues in the psychology of colour.
