This is very interesting stuff. I’m a native English speaker but also grew up learning French and other languages; to me, colour categories seem to be pretty much an arbitrary matter of convenience. There is no inherent distinction between light blue and dark blue in English, just as there is no distinction between pure and impure code in C++. You can introduce it artificially, it’s just that the language puts them in the same category.
Also, English may have only 11 “basic” colour categories, but there are loads more colour words than that, and you can get basically as specific as you like.
I also have a suspicion that I’m a tetrachromat, because I distinguish various red-orange colours that no one else seems to. Since I’m male, though, that would only be possible if I had two X chromosomes and the right mutations on both sides of my family—possible, but unlikely.
