I'd have to dig up references, but I understand it's a pretty well documented effect that having words for colors is directly related to a population seeing more distinction for those colors.

If I recall, some early societies didn't have a distinction between green and blue. Given that blue often doesnt show up naturally outside of the sky and it's reflections. And in those populations they would be much less sensitive to distinctions in blue-green.

For early societies, you might be thinking of the Greeks, though apparently it's somewhat common between languages?[1] For Greek the idea to originate from Homer's writings, with colors being more described in terms of how light or dark they are versus specific hues.[2]

Which is exactly what the article is about ;) (Well, one example of an early society that didn't distinguish between green a blue.)
