Blue is also the color human vision is worst at. You have many fewer blue color receptors than green or red. Images colored blue look more blurry than ones colored green.
That said, it's still one of the three basic colors humans can see. There was clearly an evolutionary advantage to seeing it. And I find it hard to believe that radiolab episode that said people literally didn't see blue, not just use a different word.

The hosts did keep talking about "not being able to see blue", but I believe what the guest was getting at is that without the word for blue you see it but do not perceive it (or at least as strongly as the perception of other colors). I wonder if this is related to the color/language study talked about in this episode: http://www.radiolab.org/story/211119-colors/ http://www.radiolab.org/story/211119-colors/ (the part discussing a rat study with Charles Fernyhough).
