Environment and culture shape both the colour lexicon and the genetics of colour perception

Abstract Many languages express ‘blue’ and ‘green’ under an umbrella term ‘grue’. To explain this variation, it has been suggested that changes in eye physiology, due to UV-light incidence, can lead to abnormalities in blue-green color perception which causes the color lexicon to adapt. Here, we app...
