Why Is Blue So Rare In Nature?

Duh, except for the sky… and the ocean…
Don't miss our next video! SUBSCRIBE! ►► bit.ly/iotbs_sub
↓↓↓ More info and sources below ↓↓↓
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.

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.

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.

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.

[@eco_logic]

In New Zealand we have a blue hochstetter mushroom

[@jennifermarlow.]

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. :)

[@dixen9116]

Texas bluebonnets

[@daffers2345]

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.

[@jpdemer5]

Blue flowers have the real rarity: actually-blue pigments, chemically known as anthocyanins.

[@mq830]

This is why the sky is "blue". The Sun's rays hit our atmosphere at such an angle that it reflects the Blue Light, hence lighting up our skies in a beautiful blue. And sunsets are redish-orange, because as the angle changes, of the Sun "setting", the blue is no longer the strongest colour, it is the redish-orange end of the spectrum - thus giving us our beautiful sunsets. *EDIT* - Read the Replies and Comments to this. It'll restore your faith in collectively working together as one. Humanity above all else :)

[@happypotato5499]

Ummm it doesn't have to do something with the angle the sun's rays hit earth with. It's the distance and scattering of light. In the mornings and afternoons sun is closer to the earth and blue scatters the most and that's why sky is blue and in the sunsets sun is farther from earth so blue wavelengths get scattered earlier and we see our skies as red and yellowish because red and yellow scatter lesser.

[@daffers2345]

I find this very interesting from several standpoints (biology, optics, genetics, and I'm sure plenty more). I remember learning that the elusive blue rose isn't naturally possible due to a lack of pigment. We see blue colors in other flowers and plants though. I'm curious now, what about plants, and what about minerals such as natural sapphires, turquoise, and aquamarine?

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.

[@Vysair]

Nigel Thornberry So *pure* ice was also not true blue?

[@Fajowski50]

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.

[@Vysair]

Nigel Thornberry Thank you very much for that explanation.

[@Vysair]

Nigel Thornberry But don't you mean red and green that were trapped in the ice?

[@Fajowski50]

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.

The sky isn't actually blue though, it's just reflecting the blue light during day time. That's also why it turns so many colors during sunset if I'm not wrong. So if you view the blue of the sky as its true color then the sky is actually all colors of the rainbow Its been a long time since ive red up on this though so I could be wrong in some places

However, there are some notable blue minerals. One example is azurite, a copper carbonate mineral that is often blue and is associated with the weathering of copper ore deposits. Another blue mineral is lazurite, found in lapis lazuli.
