The book *Consciousness, Color, and Content* is a comprehensive exploration of representationalism, a theory of phenomenal consciousness. It consists of eight essays divided into three parts. Part I addresses the explanatory gap and the knowledge argument, arguing that phenomenal concepts are conceptually irreducible and that questions about these gaps are not genuine. Part II delves into representationalism itself, summarizing its motivations and developing the "transparency intuition." It also examines various objections to representationalism, including real-world cases, imaginary cases, and problem cases, with detailed responses to counter-examples like the Inverted Earth and Swampman scenarios. Part III discusses broader issues, such as the nature of color and the phylogenetic dividing line between conscious and non-conscious creatures, emphasizing the objectivist account of color required by representationalism and defending it against scientific and philosophical challenges.The book *Consciousness, Color, and Content* is a comprehensive exploration of representationalism, a theory of phenomenal consciousness.
