The funny thing about colors is that they’re largely defined in culture and you only see different colors if you’ve been educated to see them. In China and I believe also in most other East Asian cultures, blue and green are traditionally regarded as the same thing.
small correction: everyone sees basically the same colours (barring stuff like colour blindness), what changes is whether we consider it a colour. Brown is the best example, most people consider it a separate colour but it’s just orange with brighter stuff around it.
