Language Affects How We Think About Colour Unlike English, the Russian language has different words for light blue and dark blue. Russian speakers asked to pick which of the two bottom squares matched the colour of the single square above responded more quickly when one of the bottom squares was called goluboy (light blue) and the other was called siniy (dark blue) than when both were referred to by the same name. English speakers took about the same amount of time.
