The hypothesis as a whole is not thoroughly discredited; color is an extremely specific case: "The main strand of domain centered research has been the research on color terminology, although this domain according to Lucy and admitted by color terminology researchers such as Paul Kay, is not optimal for studying linguistic relativity, because color perception, unlike other semantic domains, is known to be hard wired into the neural system and as such subject to more universal restrictions than other semantic domains."[1]
