This is worse than when I found out the blobfish is just a normal-ass fish that usually lives under lots of water pressure and had just inflated from the lack of it.
but then they can still set colors, that we don’t. Or at least there are some colors they can differentiate between, that we can’t.
e.g if they have a receptor for orange, yellow and red, then can differentiate between pure orange and orange that is 50% red and 50% yellow.
So both is true: We have more colors (because of brain-things), but they still have some colors, that we don’t (because of receptors).
Is this how colors work? Would we not just end up with the same result, with the Shrimps just using their one receptor to sense it, and us using ours to blend it into the same color?
Edit: thank you guys for the explanations
We can both detect orange light, but the shrimp can also detect red light mixed with yellow light. We get tricked into also seeing orange, despite no strictly orange light being there.
Think of it like sound. If we heard sound like we see light, we would hear a chord as identical to a tone somewhere in the middle of those notes. Mantis shrimp can see chords of light without any mixing, seeing both colours rather than just a colour somewhere in between.
Pink is one of the extra fun ones. You’ll notice that there is no pink in a rainbow, but most all the other colors are there. Even showing things like a bit of all the indigo and purples and blues and oranges as it blends from one bigger color to the next. It’s all by reading electromagnetic wave lengths of reflected light and the brain processing it and assigning a color to it. This also means that there’s no way to prove that the color you perceive as being blue, for instance, is the same color as what anyone else sees as blue. Your brains version of what blue looks like may be completely different.
But pink. Pink is it’s own set of weird. At no point across the visible spectrum of light is there a wavelength size that is pink. The longest visible waves of light are red and it works its way down to shorter and shorter waves until it gets to violet.
So what is pink? An imaginary color your mind made up when it receives wavelengths of the longest area of color (the reds) and the shortest (the violets/purples) at the same time. That’s pink. There is no real way for your mind to mix those wavelengths to make any known color, so your mind just says “fuck it” and made one so it could interpret that nonsense.
Wait until you hear about how the colors white, brown, and the line of purples (purple/magenta/rose) work…
It is how color works given our particular limitations. RGB and CMY only work because of our eyes, not because of nature. If somehow we could extract the frequency spectrum of the light that reaches our eyes we could know the chemical composition of some things when burned, particularly of the sun. On the other side, we are tricked into believing our screens can produce all possible colors when in reality they can produce only three.
Can you give any source for this? The text includes 2 key links and the screenshot obviously misses out on them

They trained mantis shrimp!? That’s more interesting than the color fact lol
This is where my mind went!
This is the saddest thing I’ve ever seen that had no real world implications
So its like they’re living compressed png world chosing 4bit as color depth (it’s 16 colors tho). I’m no retro gamer but some old graphics presents unbelievable level of expression with limited colors, so it’s possible they’re seeing something amazing still.
I’m just imagining the scenes in From Beyond where once Jeffrey Combs’ pineal gland pops out of his head everything becomes “so beautiful.”
(Is a pixelated blur of rainbow colors where you can barely discern what anything is lol)
Do you have a rough timestamp where that happens in the movie?
30-40 minutes in, or thereabouts.
To be fair, we don’t see like reverse engineered printing. Printing is reverse engineered seeing. If we saw like this post is claiming shrimp see, and blue was blue and green was green and yellow was yellow, we wouldn’t be able to print by mixing three colours. We’d need one pigment per photoreceptor, same as we do now.
Can someone explain to me why the mistake made about shrimp is different than the assumptions that went into speculating how other creatures perceive the world? Dogs, bees etc.
I remembered awhile ago hearing that compound eyes can see quite remarkably due to their properties, but if this is true than it’s possible that insects really do literally see multiple copies of the world out of each segment since they wouldn’t be able to average them out across a spectrum.
This means that when they invent TV they will need 9 more colors in addition to RGB.
And we had so much trouble creating a blue LED hopefully the rest are easier
This is now our mission. It’s the job of science to give these unfortunate creatures the ability to see all the colours. Get on it, molecular biologists.
I’ve always wondered what it would look like to be able to see outside the visible light spectrum
Like would it change the colors we can already perceive or would it turn making popcorn into the trippiest shit imaginable, or would it be like Lex Luthor in all-star superman and we suddenly are able to invent new genetic material or some crazy shit.
Have you seen false colour images of flowers or galaxies? There’s definitely cool things to see, especially when getting into infrared light.
dafuq you mean fake colours, is white also fake then?
The are some colors that our brains make up that don’t actually exist, they’re called impossible colors, this video about it is pretty interesting imo
That doesn’t justify calling them fake. All colors are made up in our brains. At least call them composite
fake is just an easy way to communicate the idea without going into a bunch of complex color terminology. extra-spectral is a name for them if you really want to split hairs about it. which includes both impossible and imaginary (which are also described as fictitious).
I feel it’s like saying “matter is mostly empty space and objects don’t actually touch, they repel each other”. Yes, that may be true on a physics/atomic level, but on a practical, every day level, objets are “solid” and they “touch”.
Yeah, pink/brown doesn’t “exist”. There is no “pink wavelength”. It’s “a composite”. But you can still pull a pink crayon out and everyone agrees “yeah, that’s pink”.
Saying colors don’t exist is splitting hairs in a context most people aren’t referring to.
In the case of the shrimp, it does matter because are they seeing “pink” or “red while also seeing purple separately and distinctly”? It’s asking if they are processing the colors in the same format.
I can’t see the fake colors either, so in a way I relate to the shrimp. I’ve done the overlapping an image of yellow and blue by unfocusing your eyes, where you’re supposed to see an impossible color instead of green, but I just see green. I’ve also done the ones with staring at a color then glancing at another, and it still produces very normal colors. Yellow circle then glancing at black? Just dark blue. Green then glancing at white? Regular pink. Blue then glancing at orange? Just looks red.
Pink and brown, I think?
Isn’t brown just a dark orange? I guess it would depend on the exact shade
Only 20 minutes? Was TC even trying if it’s not at least 45 minutes?
Is there at least a new contender for their place?
