The person you were responding to said that cyan feels like a completely different color to them, neither green nor blue. I had the same reaction when it gave me a color that I immediately identified as teal, and I learned my colors as a monolingual english speaker in Ohio. Therefore the supposition that all English speakers see only blue or green is an oversimplification.

I didn't say that English speakers only see blue or green. I said that those are the two basic color terms that cyan is in between, and cyan isn't a basic color term and thus collapses to one or the other if categorized under basic color terms. Same goes for teal.
