You really think they can't see clouds in the sky because they have the same word for white and blue? I think you take those studies as saying more than they said.

We do adapt our perception a little bit to fit what we need for our every day life, not for language but whats useful for us. Language matches what people need to talk about, not the other way around, if a cultures language doesn't differentiate between blue and green its because they never needed to.
