And when you look at people's brains as they're looking at colors -- say you have colors shifting slowly from light to dark blue -- the brains of people who use different words for light and dark blue will give a surprised reaction as the colors shift from light to dark, as if, "Ooh, something has categorically changed," whereas the brains of English speakers, for example, that don't make this categorical distinction, don't give that surprise, because nothing is categorically changing.
E cando vemos o cerebro das persoas mentres miran cores, se poñemos cores que cambian  lentamente de azul claro a escuro, os cerebros de quen usa palabras distintas para azul claro e escuro mostran unha reacción sorprendente cando as cores cambian, algo como "Oh, algo cambiou totalmente", pero os cerebros de falantes de inglés, por exemplo, que non fan esa distinción, non mostran esa sorpresa, porque nada cambiou totalmente.
