I remember watching a program years ago about a car manufacturer (possibly Nissan) who were trying to produce an iridescent blue material to use as upholstery. They were trying to replicate the appearance of certain butterfly wings I believe. The solution proved to be a lot more difficult than anticipated, involving many different layers of fine woven materials which, when combined, created that irridescent blue look by reflecting and refracting light. Again, the materials themselves were colourless; there were no blue pigments involved. But the result was a pretty blue iridescence... not quite as striking as the butterfly wings, but a reasonable facsimile.

So this butterfly pigment - pterobilin - is an unreacted leftover from larvae where it aids development timing. In many other butterflies it was present in larvae state too but got transformed into phorcabilin (greenish pigment) completely, since it is photo and heat sensitive. Somehow in that particular part of the olivewing it stays protected from further chemical reactions.

My wife and her coven are into collecting plants (especially mushrooms and toadstools) from nature and heating them at various temperatures and combination of other plants to dye wool and linen which they produce from sheep or flax by hand.

[@IlIlIlIlIlIlIllIlIII]

Also due to the refractive index of the cornea and anterior chamber, blue eyes will shift toward yellow/brown when viewed from the side. That's why some people claim their eye colors can change back and forth (they absolutely don't). Another bonus fact: That's pretty much the same reason the sky turns from blue to yellow to red towards the horizon at dawn.

[@someguy-k2h]

Blue was treasured in the old world, but it was never the color of royalty. Purple is the most difficult of all colors to create in nature. Purple pigments were worth several times their weight in gold. That is why all of the royal houses used purple, Tyrian purple to be exact. This was considered the most costly color and reserved only for those of nobility. The second color was gold. Not yellow, but actual gold. It was leafed, and woven into fabrics to show power and wealth. The third color was not blue but white. A pure and untarnished white, representing purity, that was not accessible to normal people without chlorine. You could get whitish with lye and sunlight, but it's not pure white. Blue came in a distant 4th, as it can be made from woad or madder.

@@RiteMoEquations Pretty sure Alex Jones was bankrupted for slandering the parents of Sandyhook but let’s not conflate gay frogs into your equation. Since this is a scientific forum, let’s take the cool fun out of the gay blue frogs and bring in some nerdy science facts: 1). Male frogs can turn female if there are not enough females in the population. 2). We don’t know if the studies that Alex Jones or RFK Jr cited over the herbocide atrozine causing chemical castration during embryonic development controlled their studies for a balanced male to female group. 3). Blackrock defense contractors are using patented microwave lasers or “masers” on civilian valuable real estate around the world including the U.S. for the aquisition of redevelopment plans and rare earth resource deposits. It appears that the color blue required a much more concentrated frequency for the masers to penetrate, leaving blue cars and homes surrounded by white pulverized ash. 4). Creek bottoms where more moisture … and frogs.. are located are completely burned to a crisp. But reports in places like Paradise California where these DEWs were used years ago are that “the frogs are coming back.” 5). But what kind of frogs are returning to creeks incinerated by masers? If we look closer, are they reflecting enough blue light to survive these onslaughts? As this video explains, a natural pigment of yellow combined with a refraction of blue light occurs in some snakes to produce the green we see. If we look at a video from recent masers shot out of Area 51 into Malibu, the YT Channel Brushjunkie shows a dead toad in the burn zone whose skin is completely in tact… but the water and blood inside was cooked from within. This means the refracting blue scales partially protected the skin but did not prevent all the maser from reaching the yellow pigment below and boiling the toad from the inside out. Anyone who wants to take up that study and analyze frog skins in maser zones don’t expect any grants or funding from most Universities or government research facilities. Blackrock owns the corporate boards, government penchants and the central banks as well. Good luck! 🐸

Many cultures had no word for blue exactly because of its elusive character. There were no blue pigments or dyes to work on the daily, so no word for it until late in the civilization's development. Greece and its 'wine dark sea' is a prime example. Dr James Fox wrote a book on the history of colour if anyone's interested in a good read.

This is weird to me because anytime you look up you see the blue sky and uf you are by water you see the blue sea. It's odd that some cultures didn't have a word for blue when they are constantly being confronted with it

@@Demiurge13 that was Fox's point. Blue was in people's world for sure, but not in their, em, instrumental world I suppose you could say. They did not 'handle' it, as such, and so, I guess, because its importance was peripheral, its naming was neglected. I think the assumption was that language developed for practicalities before abstract aesthetic concerns.

[@Reginaldesq]

@@Demiurge13 I think its quite possible to see the colour, recognise the colour but not have a word for it. Example: the only blue thing you see is the sky. Water is clear, so when you see its blue you think its a reflection of the sky, just like you see yourself in still water. So, its like your word for blue and you word for sky are the same but, since nothing else you come across is blue, you only have a word for sky.

There is a funny thing you learn about color when getting deep into Astrophotography. Color (not just blue) that we see in our everyday lives is the reflected part of the spectrum. Leaves aren't green, they absorb red and blue and reflect the green part of the electromagnetic spectrum. It's a deep dive, but our eyes evolved to detect light interpreted as colors. Color doesn't really exist.

[@SAOS451316]

That's semantics and/or philosophy gone awry, like saying nothing can be big or small because there's no platonic ideal defining them. Color is defined by what is seen and that means what's reflected rather than what's absorbed.

I mean anything that looks blue uses "tricks of light" to look blue one way or another, whether containing pigments or not.

No. Blue paint is blue because it absorbs all the other colors except blue, which it reflects back into your eyes.

[@AlexFlockhart]

@genepozniak Yes, and the sky scatters blue light through Raleigh scattering, which reflects into your eyes. Butterfly wings and feathers have nanostructures that interfere with wavelengths until blue light is the only one reaching your eyes. In my opinion all examples are things that are blue if blue light is what our eyes see.

[@Reginaldesq]

Yes, although properties of light rather than tricks. A pigment filters or blocks (subtracts) some colours. The structures referred to in the video seem to bend light to separate the colours (like a rainbow) and then only present the angle that shows blue.

Fish breeding has always shown me that better genes and stronger character are often represented by more intense colours.

I think in Started Valley I also planted ancient fruit, which are blue! How these not get covered on this channel is beyond me :D

[@bobjoatmon1993]

So my mom, her sister and their brother became convinced that 'colloidal silver' was a medical treatment and started making it at home and drinking a pint a day. Now it is true that colloidal silver is a good antibiotic but personally i thought it overhyped and refused it. The POINT IS that after a year they all started getting a blue tinge to their skin, a nice pastel lite sky blue. They stopped taking it and it took about two years before it totally disappeared. The POINT of the story is: why did they turn blue? I'd really like to know.

This reminds me of the structure of Opals. The silcate size, shape etc. makes the different colours. Mother Nature is freakin awsome

[@jamiebensson6024]

Black is my favourite colour and always has been Anton this is super interesting you do know how to pick these unusual sunjects x

[@jeffmcginnis8051]

Weird that a brown butterfly is the only blue creature on the planet

[@billywills4391]

Love the topic. Not sure why, but it is somewhat interesting and entertaining.

[@paulspaws1521]

should have mentioned how Lexus found out how to replicate these structures in their expensive blue paint. i think it's the most expensive paint as well. it has no blue pigment either but looks really good.

[@Markbell73]

If I recall correctly Anton, you also made a paper about a paper published by a Japanese scientist team that discovered that blue eyes in humans scatters blue light because lf retina structure, which also allows those humans to see color and details better in high latitude low light conditions. Apparently blue is a very rare color in nature in every case. And only ever appears as a biological advantage for some other reason, but is reproductively selected for because of it's rarity and desirability. I wpuld bet it will be discovered that even blue colored stars are only blue because of some bizarre physics based reason that is very rare and specific.

I want a blue christmas

[@jamesleatherwood5125]

Me too!

[@Reginaldesq]

Take out a huge loan and send the money to me. You will feel blue, but, I will feel great.

[@jamesleatherwood5125]

@Reginaldesq lulz! Great logic. And it achieves natures way of getting to blue without any actual blue being involved! Genius!

[@thhseeking]

I'm sure you could get that Elvis song somewhere... :P

[@jil8091]

Blue being the favorite color makes sense. A clear sky, a clean lake or ocean. It gives us a feeling of safety and longing.

In response to the sea critter that can photosynthesize, it uses the chloroplasts not free chlorophyll. Chlorophyll by itself would oxidize and capture electrons without the full structure of the chloroplast.

[@residentenigma7141]

This episode blew my mind.

[@webchimp]

There was a display technology called Mirasol that used the light interference technique to produce colours.

[@AGDinCA]

Actually, there is one more example of an animal producing true blue pigment - a fish in the dragonet family. There are two species of dragonet fish, both in the genus _Synchiropus,_ that also make use of cyanophores. They are _S. picturatus_ and _S. splendidus,_ or the psychedelic and mandarin dragonets, respectively.

[@arnorrian1]

And some Crustaceans have the blue Crustacyanin pigment.

[@ruperterskin2117]

Cool. Thanks for sharing.

[@1TakoyakiStore]

I think a lot of it has to do with chemical reactions found naturally in animals. There is a similar problem with molluscs and being able to have truely green shells. There's only one I know of off hand (emerald nerite), I'm sure there's more, but it's definitely a thing and has been noted in a few textbooks.

[@anothersquid]

I love showing that to people. I have a blue and gold macaw, but her blue feathers are actually greyish black.

[@Shacthulhu]

Blue LED is very hard to do.

[@chuckevans2792]

It was the last color invented. I had one of the first, before they switched to frequency multiplication. Very low efficiency, very high operating temp. Most blue LEDs are not blue but convert another color to blue.

[@phiend2248]

I’ve been trying to explain this to my friends and family for years, they all think I’m crazy.

[@bgsmember3650]

I've read that LCDs (liquid crystal displays) produce color in the same way as butterfly wings, through micro-structural scaffolding that manipulates which wavelengths of light are reflected.

[@JH-pt6ih]

Same with human blue eyes. No blue pigment.

[@SewingBoxDesigns]

Husky blue eyes.
