Very interesting video. It also goes to prove that much of what we see is somewhat of an illusion.

PBS has some incredible YouTube channels. I subscribe to several.

Wow, that was great! But the sciencey words are actually from Greek. There is a very cool phrase Homer uses a lot: καί μιν φωνήσας ἔπεα πτερόεντα προσηύδα .......focus on ἔπεα πτερόεντα meaning winged (or feathered) words. Homer actually saw the words flying around. Did all the Greeks or did Homer just have synesthesia? I don't know. λεπῐ́ς, too is Greek.

Thank you for posting the video! It's an interesting topic.

I'm very impatient, though, and can't sit through many videos, so I did a Google search for written information instead. Here is some information on this topic:
Why is the colour blue so rare in nature? | Faculty of Sciences | University of Adelaide

As an aside, I used to counsel people to wear blue when they went on job interviews because so many people, especially men, prefer the color blue.
