The book is a first detailed discussion of Ludwig Wittgenstein¿s Remarks on Colour, a compilation of writings on the subject from the last fifteen months of his life. The origin and significance of the remarks are explained along with a remark-by-remark guide to what Wittgenstein says. In addition to serving as an account of the thought recorded in the text, the book provides an interpretation of Wittgenstein¿s treatment of colour concepts and an account of his distinctive philosophical style. Remarks on Colour is shown to be a good way into the philosophy, to reveal a great deal about how Wittgenstein approaches philosophy, and to bring out features of his thought elided, if not missed, by more general studies, especially those that focus on more finished work.
