[Color agnosia: a brief review].

An introductory historical reminder situates the problem of color agnosia in the global frame of neuropsychological research and emphasizes the relevance of old questions. One examines later the description of agnosia, which indicates the polymorphic character of this trouble, its limits concerning linguistic and perceptual troubles, and the principal associated symptoms. The most important explanatory hypothesis are also studied, mainly according to the Italian school of Milan (conceptual and associative deficit) and the group of "La Salpétrière" in Paris (regression of past-acquisitions). The methodology then describes the most frequent means used in neuropsychology to analyze color agnosia. Finally, questions of anatomy and lesional localisation (left associative visual cortex) are also described.
