Among living things, the color blue is oddly rare. Blue rocks, blue sky, blue water, sure. But blue animals? They are few and far between. And the ones that do make blue? They make it in some very strange and special ways compared to other colors. In this video, we'll look at some very cool butterflies to help us learn how living things make blue, and why this beautiful hue is so rare in nature.

    You never notice how rare blue is, until you do, and then you (don't) see it *everywhere*. Leave a comment and let me know what you thought of this week's video! And commence the blue-pun party

    He missed the perfect chance to say "blue-tiful"

    I remember watching this 6 years ago, and I still remember this, awesome video.

    Ok here's some hypotheses for you: 1. Only primary colors can be derived from structures 2. Using every structure we know of could be combined to construct a tubing with the highest possible light absorption that would still let a specific frequency (eg blue lasers) through. 3. The blue structure in a butterfly wing originally evolved as a way to construct a more matter-efficient functional butterfly wing and blue was just a phenotypical expression of circumstance.

    Humans: Blue is rare in nature Aliens: That planet is totally Blue

    Wonderful! Subscribed after I saw my first video from this channel. Most YT content is so boring, but not if I’m learning new things!
  • @davibartav
    What a nice video. Interesting subject, well-founded, nice narration, nice edition, nice illustrations, nice animation! 👏 People that watch have no idea of how much work is required to create such a nice product like this. Nice job, guys!

    Meanwhile in a parallel universe: A butterfly has a boxes of human corpses and says "Humans are Awesome!"

    Water- Blue but not really Butterfly-Blue but not really Water=Butterfly
