Color qualia inversion scenarios have played a key role in various philosophical debates. Most notably perhaps, they have figured in skeptical arguments for the fundamental unknowability of other persons’ color experiences. For these arguments to succeed, it must be assumed that a person's having inverted color qualia may go forever unnoticed. This assumption is now generally deemed to be implausible. The present paper defines a variant of color qualia inversion—termed ‘‘color qualia compression’’—and argues that the possibility of undetectable color qualia (...) compression is immune to the objections that have been levelled against color qualia inversion arguments, and that color qualia compression scenarios support full-blown skepticism regarding other people's color experiences.

The resent paper reviews three phases in the literature on cognition and colour, and also Luria's (1976) observations of the effects that literacy and/or schooling have on colour naming and colour categorization. It is argued that Luria's own interpretation of his findings is partiafly flawed by inconsistency, and by ethnocentric presuppositions concerning mediation and abstraction. A revised interpretation is proposed that draws on Gibson's (1950, 1966) contrast between direct and indirect perceptions. It is suggested that language usage and cultural practices (...) come to exert a joint effect upon the experience of colour by selectively directing attention towards or away from the various perceptible aspects of coloured objects.
