On top of your own cones dictating whether turquoise is blue or green - this shows all the colours you see are determined by the language avaliable to you.
The more words a language has for colours the more colours people who speak that language will see (colour blindness excepted).
It's the same with things like rain or snow. Languages that are from counties that experience a lot of rain have more words to describe rain and snow than languages from counties that have little rain and snow.
If there was just the word "rain" in English there's just two types of rainy day - light rain and heavy rain - maybe be slightly n
more ifyuou introduce the word "very".
(The thresholds between the two types would vary between individuals.)
However English has more words for rain so we have words like spitting, drizzle, downpour, torrential, lashing, pelting and so on. In counties were English is spoken and there's frequent rain people will be able to decipher when to apply these words than a person not from a country with a lot of rain.
Untimely if the word turquouse didn't exist there wouldn't be an argument to be had whether it was blue or green - it would be blue or green determined by which one of those words the most people using the words appled to it.
Apologies, I've go off on a badly explained tangent - think mind is fuddled by long unexciting night!
