Basic Color Terms (BCT) seem to be dynamic

A study published in the Journal of Vision, „The modern Japanese color lexicon“ (Kuriki et al., Journal of Vision March 2017, Vol.17, 1. doi:10.1167/17.3.1), suggests that the Japanese BCT set is evolving from 11 colors (black, white, red, green, yellow, blue and brown; pink, orange, purple, grey) to 12 colors by splitting up blue into two terms (like Russian and Italian, e.g.). Interesting, though not suprising…

Oh, and by the way, the authors are wrong in claiming that „all languages have at least some color terms in their lexicons“. The famous Pirahã have no fixed color terms, so they use a descriptive term that can change from one moment to the next (e.g., a red shirt may be called blood-like).
