I found Through the Language Glass a fascinating read. One main topic in the book is names for colors. https://www.goodreads.com/book/show/8444621-through-the-language-glass https://www.goodreads.com/book/show/8444621-through-the-lang... A thing that stuck with me is how European explorers thought some natives were colorblind because they didn't have words for blue. The scientists at the time concluded that it's obviously because the natives hadn't evolved color-vision. Or weren't given color-vision by God. This theory got cast into doubt when it turned out that the natives could easily distinguish strings with different shades of blue. The book goes on to show that languages tend to add words for colors in a certain sequence. I think it was first red, then green, then yellow ad other colors and last blue. So this study looks more like it found the last languages who wouldn't have added blue were in sunny places. Not that the speaker have impaired color vision.
