Names for colours or colour-related properties are ubiquitous among natural languages, and this has made linguistic colour classification a topic of interest: are colour classifications in natural languages language-specific, or is there a more general set of principles by which such classificatory terms are organized?

It characterizes the central contemporary debates about colour naming, and the main research strategies currently in use, as well as a novel, hybrid strategy.
