See also: > Basic Color Terms: Their Universality and Evolution (1969; ISBN 1-57586-162-3) is a book by Brent Berlin and Paul Kay. Berlin and Kay's work proposed that the basic color terms in a culture, such as black, brown, or red, are predictable by the number of color terms the culture has. All cultures have terms for black/dark and white/bright. If a culture has three color terms, the third is red. If a culture has four, it has either yellow or green. * https://en.wikipedia.org/wiki/Basic_Color_Terms https://en.wikipedia.org/wiki/Basic_Color_Terms And: > Berlin and Kay also found that, in languages with fewer than the maximum eleven color categories, the colors followed a specific evolutionary pattern. This pattern is as follows: > > All languages contain terms for black and white. > If a language contains three terms, then it contains a term for red. > If a language contains four terms, then it contains a term for either green or yellow (but not both). > If a language contains five terms, then it contains terms for both green and yellow. > If a language contains six terms, then it contains a term for blue. > If a language contains seven terms, then it contains a term for brown. > If a language contains eight or more terms, then it contains terms for purple, pink, orange or gray. * https://en.wikipedia.org/wiki/Linguistic_relativity_and_the_color_naming_debate#Berlin_and_Kay https://en.wikipedia.org/wiki/Linguistic_relativity_and_the_... * https://en.wikipedia.org/wiki/Color_term https://en.wikipedia.org/wiki/Color_term
