What does it mean to be blue? The wings of a Morpho butterfly are some of the most brilliant structures in nature, and yet they contain no blue pigment -- they harness the physics of light at the nanoscale.

Saying that pigmentation color and structural color are different is kind of a misnomer, all color absorption and emission represent underlying structural properties (wavelength to atomic structure. It would be better to say that its structural interference created color. Color is just a phenomena of our minds create to represent different electromagnetic waves captured at various frequencies and intensities by cones and rods in our eyes transmitted to the brain over optical nerve for processing. At a certain level it all becomes structural. Generally the colored light generated off of the reflection of a pigmented object is due to the non uniform absorption of electromagnetic energy which causes the frequency pool of originating wave to be changed from it's previous state. Regular light absorption is structural, light reflected or absorbed based on the dimensions and arrangement of atomic structures. This is why color is useful to us, because by using the color shift caused by structures, we can infer what something is made of (Absorption spectrography & spectrographs. The blue butterfly parts have their own reflective and refractive properties but they don't match the underlying atomic structure of the petals because of the prisms created that cause most of the non blue visible light to be cancelled out, this is why when sufficiently damaging or wetting the petals, the color changes because it cancels out the prism effect of the Christmas tree structures in the wing petals. Crushing pigments doesn't cause the color of the pigment to change because the atomic structure of a pigment is uniform and does not rely on super structures to create modifying prisms, so at any break point we can expect the same absorption behavior

Not to drift away from the topic too much, but this is another piece that speaks against an intelligent creator like so many people claim there is. Evolution did this great workaround to have something seem blue without actual pigments. If there was a God, he would just have made it with pigments like on all other animals, wouldn't he?

Blue color is rare in nature, unless youre a aphid, which aphids can be any color you can imagine, including cyan and magenta or even transparent.
If we find the largest aphid we can harvest that honeydew and we can make it into drinks or sweeteners.

But everything works this way, not just this beautiful butterfly.
Even the pigments of others butterflies works the same way.
A pigment absorb and reflect specific wavelenghts of light, producing the specific color of the pigment.

No ones asking or no one saw it i need answers to this 1: 23 the pupae appears to have tiny little eyes on the outside bottom side? Im am stumped because those two tiny little things clearly look like eyes
reply

I find all this talk about the blue morpho not really being blue annoying. Don't dyes and pigment have their colors because they reflect that color? It effectively the same thing with the morpho.
reply

is anyone else here deathly afraid of butterflies? i feel like i'm alone in being afraid of butterflies, i know there are more people with a fear of moths than me but what about butterflies?
reply

If human beings, as artists, can create color, then your conclusion that we think of structural color as evolutionary work is void of logic. There is a Grand Designer of the structural color.

This video was in my recommended because I looked up videos of the Morpho Knight battle from Kirby Star Allies.
But Im grateful for the lesson, however unexpected!

reply

So that's why they called the giant mech Morpho cuz of the blue wings also the Morpho butterfly is beautiful because of the blue color
reply

We dont see much blue bc when the color go to earth well all color can pass trough our protection and blue doesnt that is why the sky is blue
reply

Oh my goodness yes the blue butterfly is one of my favorite it is got the most beautiful is blue absolutely gorgeous thank you for sharing
reply

U know my cousins and I love blue colour but I attend to be a environmentally animal lover! Than them So this butterfly is beautiful
reply

That means if you come to touch this beautiful butterfly you won't get your hands get imparted blue coloured thing?
reply

scientists aren't sure why. it's called Creator engineering that even so called scientists cannot understand it.
reply

The blue wings butterfly looks like Mothra spreading her wings behind the waterfalls and her wings became blue
reply

Phone manufacturers be like:
Let's make a phone back glass that looks like the colors of that butterfly.

reply

I thought morpho wings had blue pigment too
Oh and there is a pigment called carotene that colours carrots?

reply

So why blue then? If their wings are meant for disguise and survival, how does blue help in a green jungle?
reply

WOW! This is the most beautiful butterfly ever! Monarch Butterflies looks trash compare to this beauty!
