“…Naming may be impaired, but the ability to select a named color may be spared, as in disorders of short-term color memory [8]. Cases of color agnosia [9,10], in which patients cannot sort colors (ie, the Holgrem test, in which nonidentical skeins of wool are sorted in their color categories), are distinct from losses in color naming or memory for object color. Impairments in memory for object color are not accompanied by difficulties in naming color samples or pointing to named colors.…”

“…); these could correspond to stored descriptions of objects that are object-centred. Neuropsychological evidence shows that an impaired ability to categorise colours may coexist with intact "viewer-centred" mechanisms (De Renzi et al 1972;Sittig 1921).…”

Different explanations of color vision favor different philosophical positions: Computational vision is more compatible with objectivism (the color is in the object), psychophysics and neurophysiology with subjectivism (the color is in the head). Comparative research suggests that an explanation of color must be both experientialist (unlike objectivism) and ecological (unlike subjectivism). Computational vision's emphasis on optimally “recovering” prespecified features of the environment (i.e., distal properties, independent of the sensory-motor capacities of the animal) is unsatisfactory. Conceiving of visual perception instead as the visual guidance of activity in an environment that is determined largely by that very activity suggests new directions for research.

“…The attention of the authors, however, has been more often attracted by deficits related to colour naming, colour-sorting (so-called 1 'colour agnosia'), and colour-object association and to their prevalent occurrence in patients with lesions of the dominant hemisphere (Sittig, 1921;Lange, 1936; Kinsbourne and Warrington, 1964), than by mere impairment of colour-discrimination. Although this last symptom has long been known to follow injury to the central optic pathways in both the contralateral and the ipsilateral visual half-field (Reinhard, 1887;Best, 1917;Teuber, 1960;Critchley, 1965), the frequency of its appearance and the wavelengths of the light spectrum that are preferentially involved are still imperfectly known.…”
