This drove me crazy when I first moved to Japan–how they had a word for “green” but called some green objects “blue”. Traffic lights, for example. And it seemed very random whether or not you’re supposed to call an object green or blue, so you just have to memorize it.

There’s this fun little test you can do to see where you personally set the limit between green and blue compared to the general population.

It would be interesting to be able to group the results by country or language to see how it affects the results.

At least now we know what color there are.
