Explores the rich spectrum of problems, concepts and theories raised by the colour grey across philosophy, art and art history Explores the rich spectrum of possibilities, ideas and practices implicated by the colour and concept of grey across philosophy, art practice, theory, history and historiography Addresses the ongoing relevance of Hegel's articulation of philosophy as 'grey on grey' Provides an interdisciplinary study of philosophical and theoretical issues raised by grey, including the relationships between abstraction and immediacy, determinancy and indeterminancy, colour and colourlessness, indifference and difference, and concepts of neutrality, repetition, tautology, and equivalence Taking off from Hegel's invocation of philosophy as a painting of 'grey on grey', this collection of essays explores the rich scope of possibilities implicated by the colour and concept of grey. Crossing art history, visual studies, philosophy, anthropology and literary studies, contributions attest to the repetitious insistence of grey on grey in rethinking the ontology of artworks and images; concepts of time, technique and medium; and how its immanent logic of self-differing summons forth deadlocks and blind spots, both past and present.
