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
But do purple is even rarer?
Great
loved this video! Now we have to find dinosaur and early bird feathers to track the evolution of the structures. Same for butterflies (I doubt we will find those).
It's Okay To Be Smart 4th!
But why is blue rare in the first place? Is there something special or peculiar about the wavelength that makes it harder to produce biologically than the other colors? I feel like the answers here didn't get down to the real reason blue is rare.

Fun fact: Homer did not mention the color blue once in his famous works ‘The Iliad’ and ‘The Odyssey’. Still, the color of the sea or of the sky was described multiple times. As an Ancient Greek student: Homer used Ancient Greek terms like ‘dark red’, ‘rich purple’ or ‘light green’.
Blue did in Ancient Greek not classify as a color worth creating its own, specific term for.
Nice observation. What do you think about that? Why didn’t they?
@Prince Zuni well because it isn’t a common color
@@willmcclard206Bruh
the sky
it's not common in "nature" but it's VERY common in what you see daily
@@corner_boi the sky also isn't "blue" it changes color depending on the temperature during the day to orange, red and white and completely vanishes at night and the sea is also not completely blue because it just reflects the light.. so yeah blue is almost an illusion

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

Haha😂
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.
What exactly is 'structure '
Most primary colours can be obtained from pigments

I remember watching this 6 years ago, and I still remember this, awesome video.
Why is blue rare in nature?
Purple: hold my beer
Purple on the spectrum is in ver less in wavelength, whereas blue next to it is more. That’s why ww don’t even take purple color light as the startup for many chemistry problems and consider blue as shortest wavelength.

@@hi-mo1fz lmao 🤣
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!
Thanks so much for this video! I've often wondered whether blue truly existed very much in nature. Looks like it does, but it's rare. I'm also curious about blue in plants. Most of the blue flowers that I know of were engineered to be so.
In New Zealand we have a blue hochstetter mushroom
Hydrangeas are blue, and other colours, depending on the nutrients in the soil. You can manipulate them by putting more of a certain nutrient in the soil, but that's their nature. We have forget-me-nots, bluebells, and morning glory, off the top of my head. And what is that bulb, is it hyacinth? I was thinking of our local "Blue Flag Iris", but it's more of a purplish colour. Oh, and how can I forget, speaking of local... lupines! It's a favorite subject of mine to paint. :)
Texas bluebonnets
I was wondering about plants too after watching this video. The elusive blue rose isn't possible in nature because of a lack of pigment, but other flowers and plants have blue or purple colors. Besides the blue/bluish ones mentioned, I can think of blue sweet pea, gentian, and blue morning glory, and common speedwell (the most common in my region having flowers with distinct blue-and-white petals). Most blue flowers are more purplish, such as the lovely blue violet.
So, butterflies are you blue?
Butterfly: Well yes, but no. 2:25

blue is my favorite color, and my love for it got deeper when i watched this videom on the other hand, i've not seen butterflies in a while. they were my favorite insects since i was a child... i wonder where they go.
Blue is my favorite color and it's not even real on animals.
That's why blue is unique
U can watch it everywhere
But there are only few places where u really find it
It's my favorite color too. That's why my favorite animal is Azure Jay, she has blue and black feathers.

HvDGaMinG26 Ahahaha so witty! 😊
Get out
Sacre bleu!
Some people don’t seem to understand the difference between actual blue pigment and just a structure that looks blue. The sky and ocean aren’t actual blue pigment. What he’s saying in the video is that blue pigment in nature is very rare.
Nigel Thornberry So *pure* ice was also not true blue?
Vysair Correct. Water and glaciers can look blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than blue (short wavelength light). So when white light from the sun enters water and pure ice, it is mostly the blue that gets returned. Same reason the sky is blue.
Nigel Thornberry Thank you very much for that explanation.
Nigel Thornberry But don't you mean red and green that were trapped in the ice?
Vysair I’m not sure I understand the question, but how colors work is that whatever color something looks, it’s because that object absorbed every other color except the one that it looks. So water is absorbing all the colors,m except blue which bounces back at our eyes so we see it as blue. I hope that answered it.
Fun fact, the Blue Morpho butterfly was the inspiration behind the Lexus LC500’s “Structural Blue” paint. Lexus spent 15 years developing that color.
Blue is my favourite colour
I never knew that it was so rare
I'm glad I came to know this so I guess I liked the video.
