Communication efficiency of color naming across languages provides a new framework for the evolution of color terms.
Cognition(2020)
摘要
•Whether a color chip is chosen as a best exemplar of a color term is influenced by stimulus saturation.•The efficiency with which a color chip is communicated is not influenced by stimulus saturation.•Estimates of communication efficiency are better than focal colors for understanding color naming.•As languages evolve, communication improves for some colors before others.•Communication efficiency estimates provide a new framework for understanding color-term evolution.
